Subject: last-modified: document NUL termination
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8f5b52c62ae5fc38ac9f545539dd458977ebb235;p=thirdparty%2Fgit.git

last-modified: document NUL termination

The command git-last-modified(1) already recognizes the option '-z', and
similar to many other commands this will make the output NUL-terminated
instead of using newlines. Although, this option is missing from the
documentation, so add it.
