New auto jump function does not work when right up next a block and facing it.

The new auto jump feature does not work when the player is .300 blocks away from the block he is facing(basically the last two pixels ).

Steps to reproduce.
1) shift (crouch) right up close to the block that is to be jumped, facing the block.
2) see it not working.

In my opinion, instead of just detecting the direction of travel and whether the player could jump, it should test for the player being as close to the block as possible. This is better than the current annoying system that just keeps jumping me up.

Thank you
