Bending belts in a specific way when smart belt building causes unexpected additional belts to be built.
What did you do?
Steps to reproduce:
1. Drag a straight line of belts forwards (up in this case)

2. Without releasing the mouse, drag back along the belt (down in this case) and press "R"

3. Drag to the side, which builds more belts than expected

What did you expect to happen instead?
I'd only expect one sideways belt line to be built. IDK if it the bend should be at the end of the belt or where the cursor is, but in either case the extra belts probably shouldn't be built.

Some related issues I found when experimenting:
* If after pressing "R" you drag to the side very fast (I'm guessing multiple tiles in a tick) it'll build a disconnected belt instead:

* When dragging backwards belts the bug doesn't seem to occur, it only seems to occur when dragging belts forwards. Below the same steps are performed but the initial belt is dragged backwards:

This is on 2.0.47, no mods aside from Space Age.
