New function to prepare the mime part and any subparts for pgp signing.
2001-03-16 Jeffrey Stedfast <fejj@ximian.com> * mail-crypto.c (pgp_mime_part_sign_prepare_part): New function to prepare the mime part and any subparts for pgp signing. (pgp_mime_part_sign_restore_part): New convenience function to undo the prepare_part. (pgp_mime_part_sign): Don't assume the part passed in is a leaf part, we could very easily get a multipart (and in fact were which is why people have been having unexpected results when signing messages with attachments) and set the encoding as if it were a leaf part. Use our 2 new convenience functions to set the encoding(s) instead. svn path=/trunk/; revision=8766
