It occurred to me today what a bad idea the Comment Field is in PGP signed
messages. Altering the Comment filed does not affect the validity of the
signature, but to the non experienced PGP/GPG user it certainly appears to
be part of the message.

        It is a minimal concern.  Ben raised a valid point for those
using plugins and/or automatic processing.  For those who use plaintext
e-Mail only, they are frequently intelligent enough to realize the
horrid syntax issues.

        Regardless, it is fairly evident upon reading.  Those who would
fall for it would likely not verify the PGP signature in the first
place, which would leave them in a bad situation regardless.
