The main lose with Emacs 21 is that it does not support character classes in regexps. We use said character classes in at least one place, and I'd really rather not turn them into concat's with some new "dvc-regexp-alnum" variable, like I did with Emacs Muse. -- | Michael Olson | FSF Associate Member #652 | | http://mwolson.org/ | Hobbies: Lisp, HCoop | | Projects: Emacs, Muse, ERC, EMMS, ErBot, DVC, Planner | `-------------------------------------------------------'
