Can we have rc.subr not print a dollar sign with rcvar output?

I notice it is confusing to some students in some of my (FreeBSD) classes.

Is it needed?

If okay, I will also look for any documentation we host and fix it too
(at least for -current). And if okay, is this something that can be pulled
