[PATCH] Paper bag fix git-describe on packed tags

[PATCH] Paper bag fix git-describe on packed tags

[Shawn O. Pearce]

In 212945d ("Teach git-describe to verify annotated tag names")
we tried to access a possibly unparsed tag structure.  We must
make sure it was parsed before we try to read its tag name.

 As 212945d is already in master this probably should be
 fast-tracked there.  Whoops.  :-)

Hmmph, looks like you already fixed this with
c374b91cf295f437d438a103bfd2cf3fffcce580 ("git-describe: use tags
found in packed-refs correctly").
