There was a big merge from Emacs CVS in between.

The problem is "\s*\\('\\)?%s\\1?\s*\\'" in the new function
`mailcap-file-default-commands'.

Emacs 21 already barf when compiling this file:

--8<---------------cut here---------------start------------->8---
"\s*"
--8<---------------cut here---------------end--------------->8---

Juri, could you rewrite "\s*\\('\\)?%s\\1?\s*\\'" in an Emacs-21
compatible way?

There's another (minor?) problem with `mailcap-file-default-commands':
`replace-regexp-in-string' is not compatible with XEmacs 21.4
(cf. `gnus-replace-in-string' in `gnus-util.el').  But as this
function is not used in the rest of Gnus, it's not a big deal (it is
only used in dired-aux.el in Emacs CVS, AFAICS).

Bye, Reiner.
