Reuse the line_range_filter in builtin_diffstat() so the stat formats
count only the lines within the tracked range. When a filepair carries
line_ranges, the filter wraps diffstat_consume() as its output callback,
forwarding only the lines inside the range for counting.
flush_range_hunk() replays buffered content through diffstat_consume(),
which ignores synthetic @@ headers since it only counts '+' and '-'
lines.
Expand the output format allowlist in setup_revisions() to accept
--stat, --numstat, and --shortstat with -L.
Leave --dirstat out of the allowlist so it is rejected like any other
unsupported format. Its default mode counts each file's whole-file
byte damage via diffcore_count_changes(), outside the line-based
pipeline that the -L filter scopes, so bare --dirstat cannot honor the
tracked range. The --dirstat=lines mode could: it aggregates the same
per-file line counts as --numstat, which -L already scopes. But
accepting only that sub-mode while bare --dirstat keeps erroring is a
confusing split, so the whole format is deferred to a follow-up;
--numstat already reports the exact per-file counts within the tracked
range.
Also drop "yet" from the generic -L rejection message ("does not
yet support the requested diff format"). Some rejected formats do
not fit a line range at all, so "yet" wrongly implied they are all
just awaiting support.

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.adoc to get started, then see
Documentation/giteveryday.adoc for a useful minimum set of commands, and
Documentation/git-<commandname>.adoc 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.adoc
(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
