The function sc-attribs-%＠-addresses in the current supercite package yields different results than the one packaged with XEmacs 20.4. With the 20.4 supercite, I evaluate the following (sc-attribs-%＠-addresses "\"Jeff Miller\" <jmiller(a)smart.net&gt;&quot; "＠") and get "jmiller" as the result, which seems correct based on the doc string. "Extract the author's email terminus from email address FROM." With the current supercite, if I evaluate the above lisp, I get "Jeff" as the result. If you look at the functions in the two versions, they are quite different. 20.4: (defun sc-attribs-%＠-addresses (from &optional delim) "Extract the author's email terminus from email address FROM. Match addresses of the style ``name%[stuff].'' when called with DELIM of \"%\" and addresses of the style ``[stuff]name＠[stuff]'' when called with DELIM \"＠\". If DELIM is nil or not provided, matches addresses of the style ``name''." (and (string-match (concat "[-a-zA-Z0-9_.]+" delim) from 0) (substring from (match-beginning 0) (- (match-end 0) (if (null delim) 0 1))))) Current: (defun sc-attribs-%＠-addresses (from &optional delim) "Extract the author's email terminus from email address FROM. Match addresses of the style ``name%[stuff].'' when called with DELIM of \"%\" and addresses of the style ``[stuff]name＠[stuff]'' when called with DELIM \"＠\". If DELIM is nil or not provided, matches addresses of the style ``name''." ;; Handle X.400 addresses where G & S fields contain the sender name. (if (string-match "/[GS]=\\([-a-zA-Z0-9_.]+\\)\\|\\([-+a-zA-Z0-9_.]+\\)" from) (if (match-beginning 2) (substring from (match-beginning 2) (match-end 2)) (substring from (match-beginning 1) (match-end 1))))) You'll notice the current version never even used the delim argument! Unfortunately, I'm not sure what the correct fix is......... Jeff
