git-fetch: allow glob pattern in refspec
This adds Andy's refspec glob. You can have a single line: Pull: refs/heads/*:refs/remotes/origin/* in your ".git/remotes/origin" and say "git fetch" to retrieve all refs under heads/ at the remote side to remotes/origin/ in the local repository. Signed-off-by: Junio C Hamano <junkio@cox.net>
