Revision e00f3790b88ce61f1bdc863011a122b98b43197e authored by Johannes Sixt on 23 May 2008, 14:13:05 UTC, committed by Junio C Hamano on 23 May 2008, 22:52:20 UTC 
rev-parse --symbolic-full-name: don't print '^' if SHA1 is not a ref
 
The intention of --symbolic-full-name is to not print anything if a
revision is not an exact ref. But this command:

    $ git-rev-parse --symbolic-full-name --not master~1

still emitted a sole '^' to stdout (provided that there's no other ref at
master~1). This fixes it.
