Although I hope we can move away from CVS soon, I can't promise that
it will happen within a short time (like say, this week), so I would
be happy to go with 2 for now.

I'm assuming the functions you will be adding will be independent of
the current gnuplot backend, so there shouldn't be any signficant
stability problems caused by doing this.  If not, then we could always
open a branch for it.
