This wraps up the preparatory refactors to unify the trailer formatters.
Two patches ago we made format_trailer_info() use trailer_item objects
instead of the "trailers" string array. The strings in the array
include trailing newlines, because the string array is split up with
trailer_lines = strbuf_split_buf(str + trailer_block_start,
end_of_log_message - trailer_block_start,
'\n',
0);
in trailer_info_get() and strbuf_split_buf() includes the terminator (in
this case the newline character '\n') for each split-up substring.
And before we made the transition to use trailer_item objects for it,
format_trailer_info() called parse_trailer() (which trims newlines) for
trailer lines but did _not_ call parse_trailer() for non-trailer lines.
So for trailer lines it had to add back the trimmed newline like this
if (!opts->separator)
strbuf_addch(out, '\n');
But for non-trailer lines it didn't have to add back the newline because
it could just reuse same string in the "trailers" string array (which
again, already included the trailing newline).
Now that format_trailer_info() uses trailer_item objects for all cases,
it can't rely on "trailers" string array anymore. And so it must be
taught to add a newline back when printing non-trailer lines, just like
it already does for trailer lines. Do so now.
The test suite can pass again without the need to hide failures
with *_failure, so flip the affected test cases back to *_success. Now,
format_trailer_info() is in better shape to supersede format_trailers(),
which we'll do in the next commit.

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 and Documentation/CodingGuidelines).
Those wishing to help with error message, usage and informational message
string translations (localization l10) should see po/README.md
(a po file is a Portable Object file that holds the translations).
To subscribe to the list, send an email to git+subscribe@vger.kernel.org (see https://subspace.kernel.org/subscribing.html for details). The mailing list archives are available at https://lore.kernel.org/git/, https://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
