I think --symbolic-short makes the most sense.

However, this is not a good way to do it, I suspect. This patch most
likely will be queued to the al/symbolic-short topic branch, but you are
losing information here. You'd probably want to try substings from the
tail of the full name (e.g. symbolic-short, al/symbolic-short,
heads/al/symbolic-short, and finally refs/heads/al/symbolic-short) and
feed them to dwim_ref() and pick the shortest one that yields the same ref
unambiguously, or something like that.
By the way, I do not see why you need to cast '/'.
