I guess the solution is to write some commands for each of the boolean
variables.  For the variable foo, it could be the command toggle-foo,
and it could toggle the variable if invoked normally, set it to true
if invoked with a positive prefix arg, and set it to false if invoked
with a nonpositive prefix arg.

This would be like the other toggle commands in Emacs.

But there is one more thing: you might wish to set the switch for the
current message only, or globally.  The implementation could be by
making the variable have a local value in the current buffer.  (But
then you need to make sure you're in the message buffer when you
access the variable.)

I'm not sure what should be the user interface for the buffer-local
versus global thing.  Could be two different commands.  Doing it via
the prefix arg appears to be difficult.  Hm.

There is the command toggle-global-lazy-font-lock-mode in Emacs 21.
Maybe this could be a guideline for the command names.
