custom.el: buffer-substring-no-properties & XEmacs 19.13

[Benny Amorsen]

I am currently using sgnus-0.54, mailcrypt 3.4, and XEmacs-19.13.

XEmacs-19.13 does not implement properties on strings, which means
that buffer-substring-no-properties fails when it tries to
(set-text-properties 0 (length string) nil string). It is not a
problem with plain sgnus, the function is never called.

Mailcrypt does call the function and dies. If I remove the definition
of the function from custom.el, mailcrypt works. (It dies later when
trying to save the article to disk, but that's a different story.)

This should fix those string property bugaboos.

(if (and
     (string-match "Gnus v5.0$" gnus-version)
     (string-match "19.13 XEmacs Lucid" emacs-version))
    (defadvice set-text-properties (around ignore-strings activate)
      "Ignore strings."
      (or (stringp (ad-get-arg 3))
	  ad-do-it)))
