Not to distract from the rest of the discussion in this thread, but that
particular issue has nothing to do with the regex engine.  It is purely
a problem with the way `string(REGEX REPLACE)` is implemented.  Maybe
a better regex engine could help fix the implementation, but this is
not due to a bug in the current regex engine.
