Commit28fcc0b71a(pathspec: avoid the need of "--" when wildcard is used, 2015-05-02) allowed: git rev-parse '*.c' without the double-dash. But the rule it uses to check for wildcards actually looks for any glob special. This is overly liberal, as it means that a pattern that doesn't actually do any wildcard matching, like "a\b", will be considered a pathspec. If you do have such a file on disk, that's presumably what you wanted. But if you don't, the results are confusing: rather than say "there's no such path a\b", we'll quietly accept it as a pathspec which very likely matches nothing (or at least not what you intended). Likewise, looking for path "a\*b" doesn't expand the search at all; it would only find a single entry, "a*b". This commit switches the rule to trigger only when glob metacharacters would expand the search, meaning both of those cases will now report an error (you can still disambiguate using "--", of course; we're just tightening the DWIM heuristic). Note that we didn't test the original feature in28fcc0b71aat all. So this patch not only tests for these corner cases, but also adds a regression test for the existing behavior.

Git - fast, scalable, distributed revision control system
Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see
Documentation/giteveryday.txt for a useful minimum set of commands, and
Documentation/git-<commandname>.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with man gittutorial or git help tutorial, and the
documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt
(man gitcvs-migration or git help cvs-migration if git is
installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://public-inbox.org/git/, http://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):
- random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
- "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
- "goddamn idiotic truckload of sh*t": when it breaks
