Ramkumar Ramachandra bac1ddd0f8 sh-setup: add new peel_committish() helper ...

The normal way to check whether a certain revision resolves to a valid
commit is:

  $ git rev-parse --verify $REV^0

Unfortunately, this does not work when $REV is of the type :/quuxery.
Write a helper to work around this limitation.
