Subject: [PATCH] Require mm-uu, Don't require qp, uudecode. (mm-encode-body):
 Apply mm-charset-to-coding-system to arg of mm-encode-coding-region.
 (mm-decode-body, mm-decode-string): Rename variables which confused charset
 with coding-system. (binhex-decode-region): Don't autoload.
 (mm-body-encoding): Require message. (mm-decode-content-transfer-encoding):
 Require mm-uu in relevant cond branches.
