literal name_enable wherever possible, and ${name}_enable
when it's not, to prepare for the demise of set_rcvar().
In cases where I had to hand-edit unusual instances also
modify formatting slightly to be more uniform (and in
some cases, correct). This includes adding some $FreeBSD$
tags, and most importantly moving rcvar= to right after
name= so it's clear that one is derived from the other.
"LDMud started as a project to clean up and modernize Amylaar's LPMud
gamedriver. Primary goals are full documentation, a commented source
body and out-of-the-box support for the major mudlibs, of which the
commented source body has been pretty much completed. During the
course of work a lot of bug fixes and improvements found their way
into the driver - much more than originally expected, and definitely
enough to make LDMud a driver in its own right."
