This discussion started as commentary on my patch, right?  What else
would we be talking about?

The fact that such positions are not desirable does not mean that the
distinction is useless.  Unreal tiles are almost always `useless', but
we still have is_real_tile() or whatever it ends up as.

If you want to check a position to see if you need to wrap it, then
you should just look at the coordinates to see if they are wrapped?
Why give a toss about whether it refers to a real tile or not?  That's
just muddying the waters.

It should never be necessary to check for such things except for when
you are creating new coordinate pairs or for debugging purposes.  But
you know as well as I do that Freeciv is not there yet.
