This is the default mutt behavior.

He appears to be using a debian patch. But I guess that patch is broken
in the way it adds those extra parameters for non-ascii values of the
pgp_mime_signature_description setting.

I don't know why you need to set the disposition to "attachment" instead
of "inline". If you just need to lookout for correspondents with
clueless mail readers, try the attached patch I'm using. I wonder why
this feature does not exist in in vanilla mutt.
