[PATCHv2] remote.c: use shorten_unambiguous_ref

[Michael J Gruber]

Use the new shorten_unambiguous_ref() for simplifying the output of
upstream branch names. This affects status and checkout.

I intentionally didn't combine the line with the previous one (see
context) to make things a bit clearer.

I haven't seen more obvious place for using shorten_unambiguous_ref().
prettify_ref() is a natural candidate but is mostly used for
prettyfying refs on the remote side. git branch is covered by Jeff's
patch already.

v2 rebases onto current next containing Bert's patch which changes the
signature of shorten_unambiguous_ref().

I take it that applying that patch to next means an end to the
discussion about changing the signature ;)
