Elijah Newren 7b6ad97939 t6006: simplify, fix, and optimize empty message test
Test t6006.71 ("oneline with empty message") was creating two commits
with simple commit messages, and then running filter-branch to rewrite
the commit messages to be "empty".  This test was introduced in commit
1fb5fdd25f ("rev-list: fix --pretty=oneline with empty message",
2010-03-21) and written this way because the --allow-empty-message
option to git commit did not exist at the time.

However, the filter-branch invocation used differed slightly from
--allow-empty-message in that it would have a commit message consisting
solely of a single newline, and as such was not testing what the
original commit intended to test.  Since both a truly empty commit
message and a commit message with a single linefeed could trigger the
original bug, modify the test slightly to include an example of each.

Despite only being one piece of the 71st test and there being 73 tests
overall, this small change to just this one test speeds up the overall
execution time of t6006 (as measured by the best of 3 runs of `time
./t6006-rev-list-format.sh`) by about 11% on Linux, 13% on Mac, and
about 15% on Windows.

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
