This is the right picture for Uranus, but I hope we will not try to get
an analogue of this into civ.

I personally think that N-S wrapping without E-W wrapping should be
ditched.  It's totally unphysical.  If a user wants something like this,
he can put his monitor on it's side.

Somewhat surprisingly, the doughnut world is more physical.  However, it
must have a pole (a single one), which corresponds to the "inside" of
the torus.

To summarize, I think the following is quite reasonable:
1. If haspoles = 0, there are no special arctic strip,
otherwise there is 1 or 2 arctic strips depending on whether we have or
have not the N-S wrap.
2. Separatepoles=1 is active only when we have poles and ensures that 
each polar strip is a separate continent.

If anyone wants anything else, there is civworld.

Jason, does your patch handle single polar continent?
Ross, I fail to see the point of your criticism.  Are there any bugs in
Jason's code?  Is he not assigning continent numbers properly?  Do you
have a concrete proposal on how to make it better (if yes, you'd better
be ready to submit a patch)?  Otherwise please refrain from "no, Jason,
think, use your head" type of tone.  This is unpedagogical, to say the
least.

Best wishes,
G.
