I would think the line "----- BEGIN PGP SIGNATURE -----" would be a  
tipoff to the fact that the signed portion of the message has ended  
and data meant for an OpenPGP application's internal use is now  
beginning.  Thus, yes, I do think it's flamingly obvious that  
anything in the signature block is not part of the signed message.

Which is the entire reason why we have those "----- BEGIN" lines.  So  
that people can see the markers delineating which portions of the  
message are protected.

As has been repeated here ad nauseam, this is not a GnuPG problem.   
This is not a PGP problem.  This is not an RFC problem.  This is, at  
best, an MUA problem and should be brought up with MUA authors who  
present signed data in a format that makes it easy to mistake things.

Please, if you want to continue to beat this drum, please beat it in  
front of the right people.

Then take it up on the Enigmail list.  This is the GnuPG-Users list.
