The original reasoning for not removing section headers upon removal of the last entry went like this: the user could have added comments about the section, or about the entries therein, and if there were other comments there, we would not know whether we should remove them. In particular, a concocted example was presented that looked like this (and was added to t1300): # some generic comment on the configuration file itself # a comment specific to this "section" section. [section] # some intervening lines # that should also be dropped key = value # please be careful when you update the above variable The ideal thing for `git config --unset section.key` in this case would be to leave only the first line behind, because all the other comments are now obsolete. However, this is unfeasible, short of adding a complete Natural Language Processing module to Git, which seems not only a lot of work, but a totally unreasonable feature (for little benefit to most users). Now, the real kicker about this problem is: most users do not edit their config files at all! In their use case, the config looks like this instead: [section] key = value ... and it is totally obvious what should happen if the entry is removed: the entire section should vanish. Let's generalize this observation to this conservative strategy: if we are removing the last entry from a section, and there are no comments inside that section nor surrounding it, then remove the entire section. Otherwise behave as before: leave the now-empty section (including those comments, even ones about the now-deleted entry). We have to be extra careful to handle the case where more than one entry is removed: any subset of them might be the last entries of their respective sections (and if there are no comments in or around that section, the section should be removed, too).

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-.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):
- 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
