* tools/gpg-mail-tube.c (mail_tube_encrypt): Fix content type for an
attached message.
--
We can't use message/rfc822 if we encrypt this message as a simple PGP
file.
* tools/gpg-mail-tube.c (mail_tube_encrypt): Rename var ct_text for
clarity. Replace debug diagnostic by log_info. Assume text/plain for
missing content-type.
--
Without this fix we would create message/rfc822 attachment instead of
a text/plain attachment with the encrypted body.
* tools/gpg-mail-tube.c (oAsAttach): NEw.
(opts): Add --as-attach.
(opt): Add .as_attach.
(parse_arguments): Set it.
(mail_tube_encrypt): Detect plain text and hhandle new option.
* tools/gpg-mail-tube.c: New.
* tools/Makefile.am: Add it.
