With that strategy, we'd have to have a big initialize_defaults()
function. Which actually might not be _too_ bad since we now have
common-main.c, but:
- it sucks to keep the default values far away from the declarations
- it does carry a runtime cost. Not a huge one, but it sucks to pay it
on every program startup, even if we're not using those variables.
True, and s/even if/even though most of the time/ the situation is
even worse X-<.
