[issue3756] re.escape() does not work with bytes()

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

I don't think there are cases where re.escape is performance critical -
are there any?
By the way, it seems to me the simplest way to write re.escape() would
be to use a regexp to do the replacement. It might or might not be the
fastest.
