One problem from my previous PR, ports/21437 remains:

	"Exmh will not use pgpv to check a Multipart/MIME Clear signature.
        Since the call to pgpv is in batch mode, there is nobody to ask if
        the user would like to overwrite /dev/null. (!)"

Fix: 

The fix required hasn't changed from ports/21437 either:

	"Make batch mode PGP 5.0i calls use the "+force" option, thereby
        eliminating the dubious need to request confirmation for
        overwriting /dev/null."

	The patch to do that follows:

How-To-Repeat: 
	Send yourself a message with any kind of clear signature.
	Attempt to read it.  Exmh will refuse with an error message
	mentioning "+force".
