Tcl 'exec' assigns special meaning to its argument when they begin with
redirection, pipe or background operator. There are a number of
invocations of 'exec' which construct arguments that are taken from the
Git repository or a user input. However, when file names or ref names
are taken from the repository, it is possible to find names that have
these special forms. They must not be interpreted by 'exec' lest it
redirects input or output, or attempts to build a pipeline using a
command name controlled by the repository.
Introduce a helper function that identifies such arguments and prepends
"./" to force such a name to be regarded as a relative file name.
Convert those 'exec' calls where the arguments can simply be packed
into a list.
Note that most commands containing the word 'exec' route through
console::exec or console::chain, which we will treat in another commit.

git gui can open a merge tool when conflicts are detected (Right click
in the diff of the file with conflicts).
The merge tools that are allowed to use are hard coded into git gui.
If one wants to add a new merge tool it has to be added to git gui
through a source code change.
This is not convenient in comparison to how it works in git (without gui).
git itself has configuration options for a merge tools path and command
in the git configuration.
New merge tools can be set up there without a source code change.
Those options are used only by pure git in contrast to git gui. git calls
the configured merge tools directly from the configuration while git Gui
doesn't.
With this change git gui can call merge tools configured in the
configuration directly without a change in git gui source code.
It needs a configured "merge.tool" and a configured
"mergetool.<mergetool name>.cmd" configuration entry as shown in the
git-config manual page.
Configuration example:
[merge]
tool = vscode
[mergetool "vscode"]
cmd = \"the/path/to/Code.exe\" --wait --merge \"$LOCAL\" \"$REMOTE\" \"$BASE\" \"$MERGED\"
Without the "mergetool.<mergetool name>.cmd" entry and an unsupported
"merge.tool" entry, git gui behaves mainly as before this change and
informs the user about an unsupported merge tool. In addtition, it also
shows a hint to add a configuration entry to use the tool as an
unsupported tool with degraded support.
If a wrong "mergetool.<mergetool name>.cmd" is configured by accident,
it gets handled by git gui already. In this case git gui informs the
user that the merge tool couldn't be opened. This behavior is preserved
by this change and should not change.
"Beyond Compare 3" and "Visual Studio Code" were tested as manually
configured merge tools.

It is possible that stat information of tracked files is modified without
actually modifying the content. Plumbing commands would detect such files
as modified, so that Git GUI runs `git update-info --refresh` in order to
synchronize the cached stat info with the reality. However, this can be
an expensive operation in large repositories. As remediation,
e534f3a886 (git-gui: Allow the user to disable update-index --refresh
during rescan, 2006-11-07) introduced an option to skip the expensive
part.
The option was named "trust file modification timestamp". But the catch
is that sometimes file timestamps can't be trusted. In this case, a file
would remain listed in Unstaged Changes although there are no changes.
So 16403d0b1f (git-gui: Refresh a file if it has an empty diff,
2006-11-11) introduced a popup message informing the user about the
situation and then removed the file from the Unstaged Changes list.
Now users had to click away the message box for every file that was
stat-dirty. Under the assumption that a file in such a state is not
the only one, 124355d32c (git-gui: Always start a rescan on an empty
diff, 2007-01-22) introduced a forced (potentially expensive) refresh
that would de-list all stat-dirty files after the first notification was
dismissed.
Along came 6c510bee20 (Lazy man's auto-CRLF, 2007-02-13) in Git. It
introduced a new case where a file in the worktree can have no essential
differences to the staged version, but still be detected as modified by
plumbing commands. This time, however, the index cannot be synchronized
fully by `git update-index --refresh`, so that the file remains listed
in Unstaged Changes until it is staged manually.
Needless to say that the message box now becomes an annoyance, because
it must be dismissed every time an affected file is selected, and the
file remains listed nevertheless.
Remove the message box. Write the notice that no differences were found
in the diff panel instead. Also include a link that, when clicked,
initiates the rescan. With this scheme, the rescan does not happen
automatically anymore, but requires an additional click. (This is now
two clicks in total for users who encounter stat-dirty files after
enabling the "trust file modification timestamps" option.) However,
users whom the rescan does not help (autocrlf-related dirty files) save
half the clicks because there is no message box to dismiss.

git-gui enables the "Repository->Create Desktop Icon" item on Cygwin,
offering to create a shortcut that starts git-gui on the current
repository. The code in do_cygwin_shortcut invokes function
win32_create_lnk to create the shortcut. This latter function is shared
between Cygwin and Git For Windows and expects Windows rather than unix
pathnames, though do_cygwin_shortcut provides unix pathnames. Also, this
function tries to invoke the Windows Script Host to run a javascript
snippet, but this fails under Cygwin's Tcl. So, win32_create_lnk just
does not support Cygwin.
However, Cygwin's default installation provides /bin/mkshortcut for
creating desktop shortcuts. This is compatible with exec under Cygwin's
Tcl, understands Cygwin's unix pathnames, and avoids the need for shell
escapes to encode troublesome paths. So, teach git-gui to use mkshortcut
on Cygwin, leaving win32_create_lnk unchanged and for exclusive use by
Git For Windows.
Notes: "CHERE_INVOKING=1" is recognized by Cygwin's /etc/profile and
prevents a "chdir $HOME", leaving the shell in the working directory
specified by the shortcut. That directory is written directly by
mkshortcut eliminating any problems with shell escapes and quoting.
The code being replaced includes the full pathname of the git-gui
creating the shortcut, but that git-gui might not be compatible with the
git found after /etc/profile sets the path, and might have a pathname
that defies encoding using shell escapes that can survive the multiple
incompatible interpreters involved in the chain of creating and using
this shortcut. The new code uses bare "git gui" as the command to
execute, thus using the system git to launch the system git-gui, and
avoiding both issues.

In the current git release, git-gui runs on Cygwin without enabling any
of git-gui's Cygwin specific code. This happens as the Cygwin specific
code in git-gui was (mostly) written in 2007-2008 to work with Cygwin's
then supplied Tcl/Tk which was an incompletely ported variant of the
8.4.1 Windows Tcl/Tk code. In March, 2012, that 8.4.1 package was
replaced with a full port based upon the upstream unix/X11 code,
since maintained up to date. The two Tcl/Tk packages are completely
incompatible, and have different signatures.
When Cygwin's Tcl/Tk signature changed in 2012, git-gui no longer
detected Cygwin, so did not enable Cygwin specific code, and the POSIX
environment provided by Cygwin since 2012 supported git-gui as a generic
unix. Thus, no-one apparently noticed the existence of incompatible
Cygwin specific code.
However, since commit c5766eae6f in the git-gui source tree
(https://github.com/prati0100/git-gui, master at a5005ded), and not yet
pulled into the git repository, the is_Cygwin function does detect
Cygwin using the unix/X11 Tcl/Tk. The Cygwin specific code is enabled,
causing use of Windows rather than unix pathnames, and enabling
incorrect warnings about environment variables that were relevant only
to the old Tcl/Tk. The end result is that (upstream) git-gui is now
incompatible with Cygwin.
So, delete Cygwin specific code (code protected by "if is_Cygwin") that
is not needed in any form to work with the unix/X11 Tcl/Tk.
Cygwin specific code required to enable file browsing and shortcut
creation is not addressed in this patch, does not currently work, and
invocation of those items may leave git-gui in a confused state.

For some asynchronous operations, we build a chain of callbacks to
execute when the operation is done. These callbacks are held in $after,
and a new callback can be added by appending to $after. Once the
operation is done, $after is executed as a script.
But if we don't append a semi-colon after the procedure calls, they will
appear to Tcl as arguments to the previous procedure's arguments. So,
for example, if $after is "foo", and we just append "bar", then $after
becomes "foo bar", and bar will be treated as an argument to foo. If foo
does not accept any optional arguments, it would result in Tcl throwing
an error. If instead we do append a semi-colon, $after will look like
"foo;bar;", and these will be treated as two separate procedure calls.
Before d9c6469 (git-gui: update status bar to track operations,
2019-12-01), this problem was masked because ui_ready/ui_status did
accept an optional argument. In d9c6469, ui_ready stopped accepting an
optional argument, and this error started showing up.
Another instance of this problem is when a call to ui_status without a
trailing semicolon. ui_status never accepted an optional argument to
begin with, but the issue never managed to surface.
So, fix these errors by making sure we always append a semi-colon after
procedure calls when multiple callbacks are involved in $after.

Reduce the Tcl version requirement to 8.5 to allow git-gui to run on

variable name collision.
* py/remove-tcloo:
git-gui: create a new namespace for chord script evaluation
git-gui: reduce Tcl version requirement from 8.6 to 8.5
Evaluating the script in the same namespace as the chord itself creates
potential for variable name collision. And in that case the script would
unknowingly use the chord's variables.
For example, say the script has a variable called 'is_completed', which
also exists in the chord's namespace. The script then calls 'eval' and
sets 'is_completed' to 1 thinking it is setting its own variable,
completely unaware of how the chord works behind the scenes. This leads
to the chord never actually executing because it sees 'is_completed' as
true and thinks it has already completed.
Avoid the potential collision by creating a separate namespace for the
script that is a child of the chord's namespace.

On some MacOS distributions like High Sierra, Tcl 8.5 is shipped by
default. This makes git-gui error out at startup because of the version
mismatch.
The only part that requires Tcl 8.6 is SimpleChord, which depends on
TclOO. So, don't use it and use our homegrown class.tcl instead.
This means some slight syntax changes. Since class.tcl doesn't have an
"unknown" method like TclOO does, we can't just call '$note', but have
to use '$note activate' instead. The constructor now needs a proper
namespace qualifier. Update the documentation to reflect the new syntax.
As of now, the only part of git-gui that needs Tcl 8.5 is a call to
'apply' in lib/index.tcl::lambda. Keep using it until someone shows up
shouting that their OS ships with 8.4 only. Then we would have to look
into implementing it in pure Tcl.

A new proc delete_files takes care of actually deleting the files in
batches, using the Tcler's Wiki recommended approach for keeping the UI
responsive.
Since the checkout_index and delete_files calls are both asynchronous
and could potentially complete in any order, a "chord" is used to
coordinate unlocking the index and returning the UI to a usable state
only after both operations are complete. The `SimpleChord` class,
based on TclOO (Tcl/Tk 8.6), is added in this commit.
