py3: more robustly cast UUID to bytes

The UUID type only has __str__ implemented. So we need to cast to
bytes on Python 3.

We need an actual bytes instance here (bytestr won't do) because
the re.escape() later iterates over characters and characters
need to behave like ints, not bytes instances of length 1.

Remove a file that was added via merge. Since the file is not in parent 1,
it should not be in the diff.

  $ hg ci -m 'a=foo' a
  $ hg co -Cq null
  $ echo 123 > b
  $ hg add b
  $ hg ci -m "b"

Rename a file that was added via merge. Since the rename source is not in
parent 1, the diff should be relative to /dev/null
