From f53423b0e09d0de9584f72ac298bdfdc9e886d73 Mon Sep 17 00:00:00 2001 From: Kevin Ballard Date: Sat, 5 Apr 2008 14:28:53 -0400 Subject: git-fetch: Don't trigger a bus error when given the refspec "tag" When git-fetch encounters the refspec "tag" it assumes that the next argument will be a tag name. If there is no next argument, it should die gracefully instead of erroring.
