t: make 'test_i18ngrep' more informative on failure When 'test_i18ngrep' can't find the expected pattern, it exits completely silently; when its negated form does find the pattern that shouldn't be there, it prints the matching line(s) but otherwise exits without any error message. This leaves the developer puzzled about what could have gone wrong. Make 'test_i18ngrep' more informative on failure by printing an error message including the invoked 'grep' command and the contents of the file it had to scan through. Note that this "dump the scanned file" part is not quite perfect, as it dumps only the file specified as the function's last positional parameter, thus assuming that there is only a single file parameter. I think that's a reasonable assumption to make, one that holds true in the current code base. And even if someone were to scan multiple files at once in the future, the worst thing that could happen is that the verbose error message won't include the contents of all those files, only the last one. Alas, we can't really do any better than this, because checking whether the other positional parameters match a filename can result in false positives: 't3400-rebase.sh' and 't3404-rebase-interactive.sh' contain one test each, where the 'test_i18ngrep's pattern verbatimly matches a file in the trash directory.

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-.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.
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):
