Subject: [PATCH] Abolish variable `mime-preview-after-decoded-position'.
 (mime-preview-play-current-entity): Use `mime-play-entity'
 simply; don't switch to raw-buffer. (mime-play-entity):
 renamed from `mime-raw-play-entity'; don't expect called in
 raw-buffer. (mime-activate-mailcap-method): Don't expect
 called in raw-buffer. (mime-show-echo-buffer): Permit to
 run in preview-buffer.
