There's a similar problem in `gnus-summary-resend-message-edit'
and the patch attached below seems to solve it.  However I don't
want to install it now because it has to be verified further and
the next Emacs (containing Gnus v5.13, a.k.a. No Gnus) release
is around the corner.  So I'd add it to my TODO list instead.
