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?
Bye, Reiner.
