Very nice idea. However, it does not take care of rc_conf_files, which 
means that a variable set in /etc/rc.conf.local can not be unset that way.

Further to be _very_  sure I'd

grep -v "^${rcvar}="

to avoid removing too much from rc.conf.

Also for clarity one could remove all ^${rcvar}= entries when enabling 
${rcvar}, possibly in an extra clear function, which might also take care
of rc_conf_files.

Have I missed anything else? I would like to see this feature when its 
ready.
