[Freeciv-Dev] is_real_tile

[Cameron Morland <cjmorlan@xxxxxxxxxxxx>]

This function, in common/map.c, only checks the y co-ordinate.

int is_real_tile(int x, int y)
{
  return y >= 0 && y < map.ysize;
}

Is there some reason for this, or did someone just forget to add a

&& x >= 0 && x < map.xsize

?
