Subject: Move parse-options's skip_prefix() to git-compat-util.h
X-Git-Tag: v1.6.0-rc0~51^2~17
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=fbca58373291afa07c5b30ab562d36ce0f6174e0;p=git.git

Move parse-options's skip_prefix() to git-compat-util.h

builtin-remote.c and parse-options.c both have a skip_prefix() function,
for the same purpose. Move parse-options's one to git-compat-util.h and
let builtin-remote use it as well.
