The set_rcvar function simply returns ${name}_enable, so setting that value
explicitly in the example removes a layer of indirection, and helps make it
more clear what's happening there, which makes it a better example.

There are occasionally good reasons for making $rcvar something other than
${name}_enable, however that's considered more of an "expert" knob, and the
reasons for doing so are beyond the scope of that particular document.
