The two forms used in hg's output are 10-digit and 40-digit ids
(the latter only with --debug, IIUC). The only reason to use another
form (especially shorter) is if you type the changeset id by hand
rather than paste it, which must not be very common.

And if there are false positives from time to time, well they'll just
link to 404s (unknown ids). I don't think that's an important issue.
