Ævar Arnfjörð Bjarmason e0b9f8ae09 grep: remove redundant regflags assignments Remove redundant assignments to the "regflags" variable. This variable is only used set under GREP_PATTERN_TYPE_ERE, so there's no need to un-set it under GREP_PATTERN_TYPE_{FIXED,BRE,PCRE}. Back in 5010cb5fcc[1], we did do "opt.regflags &= ~REG_EXTENDED" upon seeing "-G" on the command line and flipped the bit on upon seeing "-E", but I think that was perfectly sensible and it would have been a bug if we didn't. They were part of the command line parsing that could have seen "-E" on the command line earlier. When `cca2c172` ("git-grep: do not die upon -F/-P when grep.extendedRegexp is set.", 2011-05-09) switched the command line parsing to "read into a 'tentatively this is what we saw the last' variable and then finally commit just once", we didn't touch opt.regflags for PCRE and FIXED, but we still had to flip regflags between BRE and ERE, because parsing of grep.extendedregexp configuration variable directly touched opt.regflags back then, which was done by `b22520a3` ("grep: allow -E and -n to be turned on by default via configuration", 2011-03-30). When `84befcd0` ("grep: add a grep.patternType configuration setting", 2012-08-03) introduced extended_regexp_option field, we stopped flipping regflags while reading the configuration, and that was when we should have noticed and stopped dropping REG_EXTENDED bit in the "now we can commit what type to use" helper function. There is no reason to do this anymore, so stop doing it, more to reduce "wait this is used under fixed/BRE/PCRE how?" confusion when reading the code, than to to save ourselves trivial CPU cycles by removing one assignment. 1.

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
