Fix similar_escape() to convert parentheses to non-capturing style.
This is needed to avoid unwanted interference with SUBSTRING behavior,
as per bug #5257 from Roman Kononov. Also, add some basic intelligence
about character classes (bracket expressions) since we now have several
behaviors that aren't appropriate inside a character class.
As with the previous patch in this area, I'm reluctant to back-patch
since it might affect applications that are relying on the prior
behavior.
