[Freeciv-Dev] BUG: When the goto or patrol poliline falls outside the map in the isometric view.

[Martin Olveyra <molv@xxxxxxxxxxxxx>]

In the isometric view, the window map and the map itself are rotated one with
each other, so there are parts of the window that the map doesnt cover. Then,
if the goto poliline falls over that region, the following assertion (and
client abortation) takes place:

civclient: goto.c:759: find_route: Assertion `normalize_map_pos(&new_x,&new_y)' 
failed.
