[O] problem with orgstruct mode in message composition

[Eric S Fraga]

Hello,

I am having a very specific problem with orgstruct mode (well,
orgstruct++ to be precise) when writing emails.

I have recently moved to using /evil/ for all my text writing in
Emacs.  This is a vi emulator, a very good one that is currently under
intense development.  I know this may sound blasphemous but I *much*
prefer vi's modal approach than emacs's modeless operation, partly
because of RSI problems and the need to avoid key chording.  But emacs
is what I live in...

Be that as it may, evil works very well generally with org.

However, in =Message= buffers, I cannot now access the usual binding for
fill-paragraph, M-q.  I get the following error message:

: orgstruct-error: This key has no function outside structure elements

when in a simple paragraph (not a list item or table).  Evil itself has
no problems with me invoking M-q in any other buffer so I think it is
somehow an interaction between evil and orgstruct++.  Even if I try

 M-: (set-local-key "\M-q" 'fill-paragraph) RET

while in a message buffer, I get the same error!

 M-x fill-paragraph RET

works, however, so it's not a problem with fill-paragraph itself.  In
fact, the bindings in org.el for orgstruct mode indicate that M-q should
invoke this function...  in going through the code, I cannot see
why the error is happening.

Can anybody advise on how to figure out what is going on?

Apologies for the long email.

Thanks,
eric
