[MlMt] Bug in preserving format=flowed text from external editors?

[Philip Paeps]

I've recently noticed some erratic behaviour with format=flowed.

I use Vim to write email and it's configured to preserve spaces at the 
end of lines and all the other space stuffing required by f=f (:setlocal 
fo+=w).  Sometimes, when I exit the editor though, I find my text 
rewrapped and the trailing whitespace missing.  But not always in all 
paragraphs.  Editing in the external editor again indeed shows the 
trailing whitespace has gone.

MailMate seems to be better at preserving trailing whitespace in replies 
than in new messages, if that helps.  For instance: I typed this message 
in Vim but the only way to get the flowed format was to remove hard line 
breaks in MailMate.

Is there a way to configure MailMate not to strip trailing whitespace 
from buffers messages edited externally?  Or perhaps to debug its 
behaviour when it gets the rewrapping wrong?

Thanks.
Philip
