A sweep of every getenv() in the tree against the environ.ini template
found five options the code answers to that the file never mentioned:
the physics trace, the spawn-zone pin, the gauge profiler, the renderer
diagnostic and the joystick-scan log. They were deliberately env-only
once - scaffolding, not settings - but scaffolding that cannot be found
is scaffolding that gets rebuilt, and RP412RENDERDIAG had already been
forgotten thoroughly enough that this sweep is what rediscovered it.
They get their own section, between the shipped configuration and the
optional extras, with the header saying what they are for: making a
claim about the game testable instead of arguable. All five ship
commented out, cost nothing when off, and none belongs in a real race.
The sweep now closes empty - there is no environment variable the game
reads that the file does not document - and the mention-check keeps it
honest from here: a build that grows a new option names it in rpl4.log
for every carried-over file.
