shortest: cache disambiguation revset
This makes it actually useful. In compared the time in my hg repo with
69.6k revisions and with a disambiguation revset of "not public()"
that matches 563 visible revisions. I ran "time hg log -T
'{shortest(node1,)}' -r 0:1000" (no revisions within the revset in
that revision range). Before this patch, it took 57s and after it took
0.7s.
