In a "git add -p" session, especially when we are not using the single-key mode, we may see 'qa' as a response to a prompt (1/2) Stage this hunk [y,n,q,a,d,j,J,g,/,e,p,?]? and then just do the 'q' thing (i.e. quit the session), ignoring everything other than the first byte. If 'q' and 'a' are next to each other on the user's keyboard, there is a plausible chance that we see 'qa' when the user who wanted to say 'a' fat-fingered and we ended up doing the 'q' thing instead. As we didn't think of a good reason during the review discussion why we want to accept excess letters only to ignore them, it appears to be a safe change to simply reject input that is longer than just one byte. The two exceptions are the 'g' command that takes a hunk number, and the '/' command that takes a regular expression. They have to be accompanied by their operands (this makes me wonder how users who set the interactive.singlekey configuration feed these operands---it turns out that we notice there is no operand and give them another chance to type the operand separately, without using single key input this time), so we accept a string that is more than one byte long. Keep the "use only the first byte, downcased" behaviour when we ask yes/no question, though. Neither on Qwerty or on Dvorak, 'y' and 'n' are not close to each other.

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
