[PATCH] PGP decryption mangles one line

[Ragnar Hojland Espinosa <ragnar.hojland@xxxxxxxxxxx>]

I discovered that the first line of PGP encrypted messages wasn't
shown in some(all?) cases.. mutt_read_mime_header use in
pgp_decrypt_part as it currently stands has an obvious problem.

Suggested patch attached.  Please Cc.
