I would really prefer to avoid all of this and just stick with wildmat the
way it's implemented right now but with the minimal change of specifying
the character set as being UTF-8.
Anything more is a rather significant change to the meaning of backslash.
I don't know how many people (if anyone) are currently taking advantage of
the fact that you can safely backslash everything in a string to ensure it
matches literally, but removing that is fairly significant. (The changes
to character classes I'm less concerned about, since in practice I think
they're pretty rarely used.)
