Alan, about displaying asteroids in assorted colors: I am indeed
thinking that this is a possibility. The new scheme for handling
doubled asteroids may lead to some very useful improvements of
this sort, and I'm holding off on actually doing much of anything
until I figure out some of the possibilities.

The idea is that, with the fix I've made thus far, asteroids can
be marked as "don't display, because it's already been shown
from COMETS.DAT". With a future fix, they could be marked
as "numerically integrate this guy". With a bit more effort, you
could say, "Put these asteroids in group A... now these in group
B... have all of the A asteroids numerically integrated and shown
in blue... have those in B shown all the time, regardless of magnitude
level", and so on.

I don't know exactly which of these is apt to happen. But I'm
trying to make sure that it'll remain possible to do such things.

Laurent, thanks for the extra details on the "asteroid becoming
a comet" bug. Given that, I was able to replicate the problem right
away and fix it a few minutes later.

Regarding the satellites displayed in orange:

It's not a bug; it's a feature.

Kevin's "crazy guess" is correct: satellites in shadow are displayed
as orange, those in sunlight are shown in yellow (by default; you can
change that color, but not the eclipsed color.)
