Ok, I see that I changed this in revision 971, in October 2010. Since then,
MIME-encapsulated forwarding, irrespective which key-binding is used, has
been forwarding all headers.

The rationale is two-fold. If people make mistakes in the forwarded
headers, the MIME might be broken and the recipients won't be able to
process the encapsulated message. Secondly, there is no harm in sending all
the headers because the recipients are expected to process the
MIME-encapsulated message and use their own formatting to view the headers.

So, if you use MIME-forwarding, you don't need
vm-forward-message-all-headers. You get all the headers in the normal
forward.
