If that's the ultimate goal, I think it would be better to have "<src>" treated as "<src>:<resolve of <src>>" instead of as "<src>:<src>" in match_refs(); and not do any special rewriting on the front end. How about this: ----- commit a5de00049f4072e3ea54ff05bc265a4b48a5ce74 Author: Daniel Barkalow <barkalow@xxxxxxxxxxxx> Date: Wed Feb 20 12:54:05 2008 -0500 Resolve value supplied for no-colon push refspecs When pushing a refspec like "HEAD", we used to treat it as "HEAD:HEAD", which didn't work without rewriting. Instead, we should resolve the ref. If it's a symref, further require it to point to a branch, to avoid doing anything especially unexpected. Also remove the rewriting previously added in builtin-push. Since the code for "HEAD" uses the regular refspec parsing, it automatically handles "+HEAD" without anything special. Passes the included test written by Junio Hamano.
