  1. Fix SIMILAR TO regex translation for character classes 

    The code that translates SIMILAR TO pattern matching expressions
to regular expressions didn't consider that brackets can be nested,
as in [[:alpha:]%], and replaced placeholders like _ and % where
it shouldn't.

Fix by tracking the nesting level of brackets while considering that
in expressions like []] and [^]] the first closing bracket is a
regular character.
