Summary: Threading/tapping with spindle running backward: no motion

Initial Comment:
With the spindle running CCW (M4), G33 and G33.1 commands result in no motion.

To reproduce:

S300 M4 G0 Z0
G33 Z-1 K.1

expected result: synchronized move to Z=-1
actual result: no motion and the "move" never completes.

Message:
looks like its related to: [emc-Bugs-3092250 ] near.9 component broken for
negative inputs

this caused spindle-at-speed detection to fail when spindle running CCW 

near.comp is now fixed and the same scenario as above now works fine for
me
