Subject: last-modified: add option '--max-depth' to help output
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=19ccdcd2a5349534f01c8611d7adcac0267a10ee;p=thirdparty%2Fgit.git

last-modified: add option '--max-depth' to help output

In previous commit option '--max-depth' was added to the documentation.
To have it also appear in the help output of `git last-modified -h`,
move the handling of '--max-depth' to parse_options() in
builtin/last-modified.c itself.

It enables us to change default behavior in a subsequent commit.
