OK, that approach seems to work.  I added one line
  export SLRN_EDITOR='/usr/bin/emacs -nw -l ~/.emacs.special.slrn'
to ~/.bashrc, and put one line
  (setq mc-gpg-user-id "1701F69C")
in ~/.emacs.special.slrn.  Now when slrn edits a post, the correct gpg
key is chosen.

However, I've now got a mailcrypt question.  When I select the body of
the message and try M-x mc-sign, the mc-sign-region command is not
available.  But if I sign the whole file (including, wrongly, the
headers) then undo it, when I hit M-x again, the mc-sign and
mc-sign-region commands are both available.  Why is this, and how can
I make mc-sign-region available from the start?
