[2.0.72] Underground pipe length visualization extends into empty space, underground belt does not

When holding an underground pipe the length visualization will show up when the pipe is one space into empty space. For an underground belt the visualization does not show up when the belt is in empty space. It seems like it should be consistent between the two.

I am not considering this inconsistency to be bug-report worthy. Underground pipes are checking tile collisions only with the tiles between the pipe ends while the underground belts check for tile collisions on tiles between the belt hats and directly under them which means the underground belt stops rendering the visualisation first because there is already a space tile breaking the connection while pipe to ground does not see the space tile yet. Those 2 systems are independent and have different restrictions (underground belts are always 1x1 entities while underground pipe connections can appear on any entity with fluid boxes including entities that are larger than 1x1 and so deciding if tile under the fluid box end should or should not be included in the collide check is non trivial).
Given there is nothing broken, i will keep current behavior as is.
