master fb32368 2/2: Fix PGP verification buttons (which would have cached results)

[Lars Ingebrigtsen]

branch: master
commit fb32368efdaf11ae0e6b3a28f4a167886caa4c9d
Author: Lars Ingebrigtsen <larsi@gnus.org>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    Fix PGP verification buttons (which would have cached results)
    
    * lisp/gnus/mm-uu.el (mm-uu-pgp-signed-extract): `format' was used
    here to guarantee a new, fresh string (since it's destructively
    modified), but that's apparently not the case any more.  Use
    `substring' instead, which is documented to do this.
