Omitting two numbers, one of which is zero, is easily no more a win than
the cost of having two different nearly-identical commands. Just consider
C/c and S/s; is it really worth it?

I have to admit to being very confused about what you're trying to do.
What's wrong with A/a? It seems to be equivalent to arcTo(). Is it arc()
that you want to add? I'm very confused.
