Subject: [PATCH] Define method functions of mel. (mime-insert-encoded-file):
 Use `mel-define-method'; abolish
 `quoted-printable-insert-encoded-file'.
 (mime-write-decoded-region): Use `mel-define-method';
 abolish `quoted-printable-write-decoded-region'. - Move
 `q-encoding-printable-char-p' and
 `q-encoding-encoded-length' to mel.el.
