Without this patch, the 'stg uncommit -t patch' fails with 'Unknown
revision: patch'. With the patch applied, it still fails but with
'Commit ... does not have exactly one parent'. I don't say that the
first one is good but I don't think the latter is clearer. The 'stg
uncommit --help' states that the '--to' option takes a commit argument
but if one passes a patch name the error message gets pretty
confusing.

Actually, 'Commit ... does not have exactly one parent' means that stg
misinterpreted the patch name as some non-existing hash and started
iterating back until it hit the first merge.

Perhaps stgit should make sure that the hash is valid before walking the
commit tree.  If it's not, stgit could provide a better message.
