I guess Emacs should run all email addresses through a check for Unicode confusability and direction markers and all that stuff, too. (Which got a lot of work lately in a display context.) Do we have a predicate somewhere that says whether a string is suspicious based on confusables and r2l markers and stuff? --=20 (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
