Functions in Emacs are generally on the DWIM side, so we could make a new `regexp-replace' function be more well-defined. That is, it could be always-FIXEDCASE and never LITERAL. > The SUBEXP argument, I'm not so sure about. Yeah, that one is actually useful.

If we allow a bunch of regexp/replacement pairs, then I guess that'd be necessary anyway. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
