Revision 045a476f91a9a308c823a2709977163238baa3fd authored by Miklos Vajna on 31 October 2008, 23:25:44 UTC, committed by Junio C Hamano on 01 November 2008, 05:41:55 UTC 
update-ref --no-deref -d: handle the case when the pointed ref is packed
 
In this case we did nothing in the past, but we should delete the
reference in fact.

The problem was that when the symref is not packed but the referenced
ref is packed, then we assumed that the symref is packed as well, but
symrefs are never packed.
