Hey Bob, why don't we make a ham rule for PGP signatures?

body     PGP_SIG  /-----BEGIN PGP SIGNATURE-----/
describe PGP_SIG  Looks like a PGP-signed message.
score    PGP_SIG  -1.3

Of course, in theory spammers could start including things that look like 
PGP signatures.  But since most people don't use PGP or GnuPG, we don't 
have to worry about this.

Later of, if spammers start to add fake PGP signatures, we can call an 
external program to check the signature.  Emails whose signatures are 
recognized would automatically accepted.  Having an un-recognized PGP 
signature might even count as a spam score.

Thoughts?
