9d2a24864e Merge branch 'ak/commit-only-allow-empty' into maint
"git commit --allow-empty --only" (no pathspec) with dirty index
ought to be an acceptable way to create a new commit that does not
change any paths, but it was forbidden, perhaps because nobody
needed it so far.

* ak/commit-only-allow-empty:
  commit: remove 'Clever' message for --only --amend
  commit: make --only --allow-empty work without paths

Update the error messages from the dumb-http client when it fails
to obtain loose objects; we used to give sensible error message
only upon 404 but we now forbid unexpected redirects that needs to
be reported with something sensible.

* jk/http-walker-limit-redirect:
  http-walker: complain about non-404 loose object errors
  http: treat http-alternates like redirects
  http: make redirects more obvious
  remote-curl: rename shadowed options variable

1797dc5176 CodingGuidelines: clarify multi-line brace style
There are some "gray areas" around when to omit braces from
a conditional or loop body. Since that seems to have
resulted in some arguments, let's be a little more clear
about our preferred style.

3f05402ac0 Documentation/bisect: improve on (bad|new) and (good|bad)
The following part of the description:

git bisect (bad|new) [<rev>]
git bisect (good|old) [<rev>...]

may be a bit confusing, as a reader may wonder if instead it should be:

git bisect (bad|good) [<rev>]
git bisect (old|new) [<rev>...]

Of course the difference between "[<rev>]" and "[<rev>...]" should hint
that there is a good reason for the way it is.

But we can further clarify and complete the description by adding
"<term-new>" and "<term-old>" to the "bad|new" and "good|old"
alternatives.

03920ac69b asciidoctor: fix user-manual to be built by asciidoctor
The `user-manual.txt` is designed as a `book` but the `Makefile` wants

fc01a5d26a submodule update documentation: don't repeat ourselves
The documentation for the `git submodule update` command, repeats itself
for each update option, "This is done when <option> is given, or no
option is given and `submodule.<name>.update` is set to <string>.

Avoid these repetitive clauses by stating the command line options take
precedence over configured options.

Also add 'none' to the list of options instead of mentioning it in the
following running text and split the list into two parts, one that is
accessible via the command line and one that is only reachable via the

c026557a37 versioncmp: generalize version sort suffix reordering
The 'versionsort.prereleaseSuffix' configuration variable, as its name
suggests, is supposed to only deal with tagnames with prerelease
suffixes, and allows sorting those prerelease tags in a user-defined
order before the suffixless main release tag, instead of sorting them
simply lexicographically.

However, the previous changes in this series resulted in an
interesting and useful property of version sort:

  - The empty string as a configured suffix matches all tagnames,
    including tagnames without any suffix, but

  - tagnames containing a "real" configured suffix are still ordered
    according to that real suffix, because any longer suffix takes
    precedence over the empty string.

Exploiting this property we can easily generalize suffix reordering
and specify the order of tags with given suffixes not only before but
even after a main release tag by using the empty suffix to denote the
position of the main release tag, without any algorithm changes:

  $ git -c versionsort.prereleaseSuffix=-alpha \
        -c versionsort.prereleaseSuffix=-beta \
        -c versionsort.prereleaseSuffix="" \
        -c versionsort.prereleaseSuffix=-gamma \
        -c versionsort.prereleaseSuffix=-delta \
        tag -l --sort=version:refname 'v3.0*'
  v3.0-alpha1
  v3.0-beta1
  v3.0
  v3.0-gamma1
  v3.0-delta1

Since 'versionsort.prereleaseSuffix' is not a fitting name for a
configuration variable to control this more general suffix reordering,
introduce the new variable 'versionsort.suffix'.  Still keep the old
configuration variable name as a deprecated alias, though, to avoid
suddenly breaking setups already using it.  Ignore the old variable if
both old and new configuration variables are set, but emit a warning
so users will be aware of it and can fix their configuration.  Extend
the documentation to describe and add a test to check this more
general behavior.

Note: since the empty suffix matches all tagnames, tagnames with
suffixes not included in the configuration are listed together with
the suffixless main release tag, ordered lexicographically right after
that, i.e. before tags with suffixes listed in the configuration
following the empty suffix.

3a42980f9e ref-filter: Do not abruptly die when using the 'lstrip=<N>' option
Currently when we use the 'lstrip=<N>' option, if 'N' is greater than
the number of components available in the refname, we abruptly end
program execution by calling die().

This behavior is undesired since a single refname with few components
could end program execution. To avoid this, return an empty string
whenever the value 'N' is greater than the number of components
available, instead of calling die().

it can also be removed.  This patch also removes the old functionality

9574901c02 giteveryday: unbreak rendering with AsciiDoctor
The "giteveryday" document has a callout list that contains a code
block. This is not a problem for AsciiDoc, but AsciiDoctor sadly was
explicitly designed *not* to render this correctly [*1*]. The symptom is
an unhelpful

	line 322: callout list item index: expected 1 got 12
	line 325: no callouts refer to list item 1
	line 325: callout list item index: expected 2 got 13
	line 327: no callouts refer to list item 2

In Git for Windows, we rely on the speed improvement of AsciiDoctor (on
this developer's machine, `make -j15 html` takes roughly 30 seconds with
AsciiDoctor, 70 seconds with AsciiDoc), therefore we need a way to
render this correctly.

The easiest way out is to simplify the callout list, as suggested by
AsciiDoctor's author, even while one may very well disagree with him
that a code block hath no place in a callout list.

Alternatively git-p4.retries could be made opt-in.
But since only very old, barely maintained p4 versions don't support
the '-r' option, the setting-retries-to-0 workaround would do.

The "-r retries" option is present in Perforce 2012.2 Command Reference,

3cde4e02ee diff: retire "compaction" heuristics
When a patch inserts a block of lines, whose last lines are the
same as the existing lines that appear before the inserted block,
"git diff" can choose any place between these existing lines as the
boundary between the pre-context and the added lines (adjusting the
end of the inserted block as appropriate) to come up with variants
of the same patch, and some variants are easier to read than others.

We have been trying to improve the choice of this boundary, and Git
2.11 shipped with an experimental "compaction-heuristic".  Since
then another attempt to improve the logic further resulted in a new
"indent-heuristic" logic.  It is agreed that the latter gives better
result overall, and the former outlived its usefulness.

Retire "compaction", and keep "indent" as an experimental feature.
The latter hopefully will be turned on by default in a future
release, but that should be done as a separate step.

48d5014dd4 config.abbrev: document the new default that auto-scales
We somehow forgot to update the "default is 7" in the
documentation.  Also give a way to explicitly ask the auto-scaling
by setting config.abbrev to "auto".

74ed43711f grep: enable recurse-submodules to work on <tree> objects
Teach grep to recursively search in submodules when provided with a
<tree> object. This allows grep to search a submodule based on the state
of the submodule that is present in a commit of the super project.

When grep is provided with a <tree> object, the name of the object is
prefixed to all output.  In order to provide uniformity of output
between the parent and child processes the option `--parent-basename`
has been added so that the child can preface all of it's output with the
name of the parent's object instead of the name of the commit SHA1 of
the submodule. This changes output from the command
`git grep -e. -l --recurse-submodules HEAD` from:

      HEAD:file
      <commit sha1 of submodule>:sub/file

to:

      HEAD:file
      HEAD:sub/file

0281e487fd grep: optionally recurse into submodules
Allow grep to recognize submodules and recursively search for patterns in
each submodule.  This is done by forking off a process to recursively
call grep on each submodule.  The top level --super-prefix option is
used to pass a path to the submodule which can in turn be used to
prepend to output or in pathspec matching logic.

Recursion only occurs for submodules which have been initialized and
checked out by the parent project.  If a submodule hasn't been
initialized and checked out it is simply skipped.

In order to support the existing multi-threading infrastructure in grep,
output from each child process is captured in a strbuf so that it can be
later printed to the console in an ordered fashion.

To limit the number of theads that are created, each child process has
half the number of threads as its parents (minimum of 1), otherwise we
potentailly have a fork-bomb.

fe05033407 Merge branch 'jk/quote-env-path-list-component'
A recent update to receive-pack to make it easier to drop garbage
objects made it clear that GIT_ALTERNATE_OBJECT_DIRECTORIES cannot
have a pathname with a colon in it (no surprise!), and this in turn
made it impossible to push into a repository at such a path.  This
has been fixed by introducing a quoting mechanism used when
appending such a path to the colon-separated list.

  t5615-alternate-env: double-quotes in file names do not work on Windows
  t5547-push-quarantine: run the path separator test on Windows, too
