(progn (string-match "\\(x\\)\\|\\(y\\)" "x") (match-data)) => (0 1 0 1) I stand corrected. Hey, can I rely on that? It would probably speed up some code of mine where I have to scan for the only non-nil match-beginning. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-devel
