Teleporters break the route search and enemies walk past the shortcut

You add a pair of teleporters and the enemies still take the long walk, even though the portal is far quicker. The search was told a rule that portals break. Here is which one, and the one-line change that lets the shortcut win.

Why this works

The search steers by a guess of the distance left, and it only works if that guess is never too big. A teleporter can beat the straight line, so the guess has to include it, or the search settles for a longer route.

When not to use it

Skip it on tiny maps or when portals are one-way traps or random: a plain search that tries everything is fast enough and cannot be misled. Also skip it if enemies should not know about portals, so the player can outwit them.
