Re: gnus: pgg-gpg-lookup-key uses wrong regular expression

[Simon Josefsson <jas@extundo.com>]

Let me know if this works or not.  Apparently, the behaviour of the
new split-string was intentional, so it is no longer possible to use
the function portably...  Well, it was useful while it lasted.

	* pgg-gpg.el (pgg-gpg-lookup-all-secret-keys)
	(pgg-gpg-lookup-key): Use regexp match instead of
	split-string (split-string is different between emacs 21.2 and
	21.4).  Reported by ultrasoul@ultrasoul.com (David D. Smith).
