PGP does have a word wrap function.  Since some mailers do their
wrapping after PGP has been run on the mail, that would break the
signature.  To help avoid this, PGP can wrap as part of the signing
function.  The idea is you make PGP wrap at a lower value than your
mail client, so the mail client never has anything to do.

GnuPG never wraps.  Mailers in the *nix world tend to handle filtering
properly so it is not necessary.  I'm not sure if WinPT wraps or not.
