gpg: New option --mimemode.
* g10/gpg.c (oMimemode): New. (opts): Add --mimemode. (main): Use --mimemode only in rfc4880bis compliance mode. * g10/options.h (struct opt): Add field "mimemode". * g10/build-packet.c (do_plaintext): Allow for mode 'm'. * g10/encrypt.c (encrypt_simple, encrypt_crypt): Use 'm' if requested. * g10/plaintext.c (handle_plaintext): Handle 'm' mode. * g10/sign.c (write_plaintext_packet): Handle 'm' mode. (sign_file, sign_symencrypt_file): Use 'm' if requested.
Thsi patch prepares for a proposed change in RFC4880bis to support a
MIME flag. A literal data packet with the mime flag set is handled
like a 't' or 'u' but CR are not removed. The PLAINTEXT status line
will also indicate a MIME content.
If --mimemode is used without --rfc4880bis 't' will be used.
