* bug#9392: 24.0.50; rmail-forward produces messages in unsupported format that cannot be customized away

Typing `f' (rmail-forward) in an Rmail buffer produces this line:

  <#part type=message/rfc822 disposition=inline raw=t>

followed by the headers and the body of the forwarded message.  This
happens because rmail-forward was changed some time ago to call
message-forward-make-body-mime (through
rmail-insert-mime-forwarded-message-function), like this:

	    (if (or rmail-enable-mime rmail-enable-mime-composing)
		(funcall rmail-insert-mime-forwarded-message-function
			 forward-buffer)
	      (insert "------- Start of forwarded message -------\n")

Q1: Where is this format documented? any RFCs or some such?  I
couldn't find any spec with this format, but I don't really know what
to look for, not being an expert on these issues.

Q2: Which MUAs support this format on reception, and can show the
forwarded message in a reasonably useful form?  Rmail certainly
doesn't; I also tried Outlook and a couple Web-based mail systems --
none of them did.  What I see is the raw message, complete with b64
encoded attachments -- entirely illegible.  If this format is not
widely supported, why does it make sense to generate it by default?
At the very least, Rmail should support that, or stop using it by
default.

The bug: The way the code invoking message-forward-make-body-mime is
written, it is impossible to customize away this "feature" without
disabling rmail-enable-mime, which disables a lot of other useful
features.  At the very least, it should be possible to disable this
"feature" alone, by customizing rmail-enable-mime-composing.  This
could be as a simple as replacing `or' with `and' in the above
condition.
