After looking at this for an hour or two, there's no way to tell
whether the backend variable has been specifically set to 0, instead
of defaulting to 0. At least without reworking how the be structs
work (adding an initialization step that sets them to defaults
provided by params). AFAICT.
The following are identical in behavior, and therefore params can't
be /conditionally/ overridden:
.initial_health = 0;
# .initial_health = 0;
So you can't do "-p initial_health=1" and then set ".initial_health=0".
So it's an either/or proposition. I like the per-backend setting
myself, but if the general opinion is that a global param is better, I
can create a different patch.
