I'm still having some difficulty getting the effect I want since the
great message.el switch.

Before the switch, I had a cheesy function defined on `\C-c\C-w' in
mail-mode-map that would insert the contents of "~/.sig" normally, but
if given a prefix argument, would insert the contents of
"~/.signature" instead.

What is the cleanest way to get this behavior back?
