[PATCH] MH-E: don't automatically download external-body parts

[Mike Kupfer]

Is the attached okay for emacs-26, or should it go to master?  It makes
MH-E behave more like Gnus when displaying a message that has a MIME
external-body part.

regards,
mike

Subject: [PATCH] MH-E: don't automatically download external-body parts

* lisp/mh-e/mh-mime.el (mh-mime-display-single): Use
mm-automatic-display-p to verify that a part should be
displayed before doing the inline checks (SF#475).
