py3: bytestr() bytes to get bytechar while iterating on it

Iterating on bytes give you ascii values instead of bytechr so we need to wrap
the bytes in pycompat.bytestr() to get bytechr while iterating.

Test for issue2043: ensure that 'merge -P' shows ancestors of 6 that
are not ancestors of 7, regardless of where their common ancestors are.
