And note that re-escape should be easy to write.  I guess the main issue
would be to decide what escape character to use (assuming "(" is used for
regexp-grouping, what should be used to match a plain open-parenthesis?
"\(" is not an option since it's the same string as "(", so you either
have to go with "\\(" which (as we know) sucks, or choose another escape
char than backslash).
