1. Since the example program is called doormand, update the references
to doorman in the script and examples to match the name of the program,
as it is typically done.
2. Fix the comments about the variables to avoid line wrap past 80 columns
3. Re-sort the variables (such as command, etc.) to be in the order that
they are generally listed in the base scripts, and in rc(8).
4. Simplify the rcvar variable to be what `set rcvar` would return anyway
