This patch is to fix a problem reported by Miles Nordin <carton@Ivy.NET> in
PR27034.  SEMI development also had addressed the same problem and solved
another way than Miles Nordin reported.  According to Katsumi Yamaoka
<yamaoka@jpl.org> this ``regexp'' fix, already done in the SEMI repository,
is more generic, can avoid problems across Emacs versions , so I (uebayasi@)
decided to adopt this.  This patch follows the original file's license.

* pgg-gpg.el (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).
