Subject: [PATCH] git-gui: Teach start_push_anywhere_action{} to notice when remote is a mirror.

From: Mark Burton <[email-masked]>
Date: Tue, 2 Dec 2008 15:15:02 +0000

When the destination repository is a mirror, this function goofed by still
passing a refspec to git-push. Now it notices that the remote is a mirror
and holds the refspec.

 This patch stops git-gui from annoying git-push when the remote is a
 mirror. A further enhancement would be to disable the branch names list
 in the dialog when the selected destination is a mirror. As it stands, you can
 select a branch name from the list but it will be ignored (this could possibly
 confuse/annoy people). But that's a bunch more work so I'm stopping here for
 now.
