It seems to only get mentioned once and never set:
$ git grep sha1_short perl
perl/Git/SVN/Log.pm: } elsif (/^${esc_color}:\d{6} \d{6} $::sha1_short/o) {
Looks like it got renamed, and this reference was somehow missed?
$ git log -1 -Ssha1_short perl

perl: create and switch variables for hash constants
git-svn has several variables for SHA-1 constants, including short hash
values and full length hash values. Since these are no longer SHA-1
specific, let's start them with "oid" instead of "sha1". Add a
constant, oid_length, which is the length of the hash algorithm in use
in hex. We use the hex version because overwhelmingly that's what's
used by git-svn.
