The answer to that I still believe to be > yes. Already Emacs 20.7 and Emacs 21.3 differ in some aspects. IIRC, some examples not supported by Emacs 20.7 are shy groups `\(?: ... \)', repetition `\{N,M\}' and character classes (string-match "[[:digit:]]" "1"). CMIIW. See e.g. the conditional in `gnus-button-url-regexp' or missing of \{N,M\} in `gnus-button-mid-or-mail-heuristic-alist'. We could simplify these expressions, if support for Emacs 20 would be dropped some day. Maybe already in No Gnus?
