description:
run_rc_command - don't prefix the rcvar variable name with the dollar sign.

The output without the dollar sign is less confusing as it's actual
valid shell syntax:

  $ /etc/rc.d/foo rcvar
  # food
  food=YES

Brought up on tech-userlevel@ by Rocky Hotas with some LGTMs from
other people and no objections.

We still refer to '$food' in warnings/errors though.
