config: allow tweaking whitespace between value and comment Extending the previous step, this allows the whitespace placed after the value before the "# comment message" to be tweaked by tweaking the preprocessing rule to: * If the given comment string begins with one or more whitespace characters followed by '#', it is passed intact. * If the given comment string begins with '#', a Space is prepended. * Otherwise, " # " (Space, '#', Space) is prefixed. * A string with LF in it cannot be used as a comment string. Unlike the previous step, which unconditionally added a space after the value before writing the "# comment string", because the above preprocessing already gives a whitespace before the '#', the resulting string is written immediately after copying the value. And the sanity checking rule becomes * comment string after the above massaging that comes into git_config_set_multivar_in_file_gently() must - begin with zero or more whitespace characters followed by '#'. - not have a LF in it. I personally think this is over-engineered, but since I thought things through anyway, here it is in the patch form. The logic to tweak end-user supplied comment string is encapsulated in a new helper function, git_config_prepare_comment_string(), so if new front-end callers would want to use the same massaging rules, it is easily reused. Unfortunately I do not think of a way to tweak the preprocessing rules further to optionally allow having no blank after the value, i.e. to produce [section] variable = value#comment (which is a valid way to say section.variable=value, by the way) without sacrificing the ergonomics for the more usual case, so this time I really stop here.

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):
