The user interface provided by the command loop in git-add--interactive gives the impression that subcommands can only be launched by entering an integer identifier from 1 through 8. A "hidden" feature is that any string can be entered, and a regex search anchored at the beginning of the string is used to find the uniquely matching option. This patch makes this feature a little more obvious by highlighting the first character of each subcommand (for example "patch" is displayed as "[p]atch"). A new function is added to detect the shortest unique prefix and this is used to decide what to highlight. Highlighting is also applied when choosing files. In the case where the common prefix may be unreasonably large highlighting is omitted; in this patch the soft limit (above which the highlighting will be omitted for a particular item) is 0 (in other words, there is no soft limit) and the hard limit (above which highlighting will be omitted for all items) is 3, but this can be tweaked. The actual highlighting is done by the highlight_prefix function, which will enable us to implement ANSI color code-based highlighting (most likely using underline or boldface) in the future.

//////////////////////////////////////////////////////////////// GIT - the stupid content tracker //////////////////////////////////////////////////////////////// "git" can mean anything, 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 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. It was originally written by Linus Torvalds with help of a group of hackers around the net. It is currently maintained by Junio C Hamano. Please read the file INSTALL for installation instructions. See Documentation/tutorial.txt to get started, then see Documentation/everyday.txt for a useful minimum set of commands, and "man git-commandname" for documentation of each command. CVS users may also want to read Documentation/cvs-migration.txt. Many Git online resources are accessible from http://git.or.cz/ including full documentation and Git related tools. 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. 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 http://marc.theaimsgroup.com/?l=git and other archival sites. The messages titled "A note from the maintainer", "What's in git.git (stable)" and "What's cooking in git.git (topics)" and the discussion following them on the mailing list give a good reference for project status, development direction and remaining tasks.
