[PATCH] Use the message cite variable instead of a hard coded function

[Todd]

It's defaulted to message-cite-original in Emacs 24, and may have been
back to Emacs 22.3 ("This variable was introduced, or its default value
was changed, in version 22.3 of Emacs.").  

I can re-work the patch to fall back to message-cite-original if it's
been unset, if that's preferred.

- Todd
