I'm guessing if I really sent a block like that to a remailer, the remailer would hork because of the prepended "- "s. I know that sometimes people's public keys they've posted to a list look like that, and when I try to add them to PGP, it horks, and I've got to go into a text editor and remove the "- ", and then add it to my keyring.

PGP does this... Not only does it complicate nested PGP signed messages, but if you pgp-sign an entire MIME message (i.e. by sending it to the autosigning service) instead of placing the signed doc inside the MIME boundries, it can cause mail readers to not recognize the MIME boundries and display the letter as normal ASCII-Mail. andrew
