M19 Spindle Orient currently (2.6.3, 2.7.0~pre2, 2.8.0~pre1) has some surprising behavior.

  • M19 without an R-word is accepted, but results in no orient happening. Probably a default orient angle of 0 should be used in this situation.
  • M19 without a Q-word is accepted, but results in no wait. It's unclear if the Q-word should be optional, and what should happen if it's missing.

The issue was discussed briefly on IRC here:
http://psha.org.ru/irc/%23linuxcnc-devel/2014-10-29.html

We should figure out how M19 should behave, then make it do that, and test that it does that.
