I see.  That's a good idea.  Perhaps we can abolish the variable
mm-auto-save-coding-system and set the default value for
message-draft-coding-system to frumple (or iso-2022-7bit).

Since not to bind the value for coding-system-for-read is
required to utilize that function, what should we do if there is
no such header?  Or isn't there nothing to do?

In addition, it is required that the coding header should be
untouchable by a user.  In order to ensure it, we will add the
header using write-contents-hooks and remove it before starting
edit of a draft.  Haven't I made a mistake in my idea?
