I think --abbrev-ref can handle much more than just shortening symrefs,
though:
E.g. resolving other symbolic names:
$ git rev-parse --abbrev-ref @{u}
origin/master
Or resolving any arbitrary name you happen to have:
$ git rev-parse --abbrev-ref refs/heads/master
master
Even ones that aren't fully qualified (which would be tough to do with
simple pattern substitution):
$ git rev-parse --abbrev-ref remotes/origin/master
origin/master
Or handling ambiguities during abbreviation:
$ git tag master
$ git rev-parse --abbrev-ref HEAD
heads/master
