Right, MIN_LIMIT and MAX_LIMIT are not handled by stepgen or
any motion interface hardware, they are handled much higher
in LinuxCNC. To reach a smooth deceleration right at the
limit position requires it to be limited before the
trajectory planner. So, these parameters are picked up out
of the [JOINT_n] stanza by something in the motion section.
Even the G-code interpreter knows about them, as you will
get "program exceeds +X limit at line 1234" messages when
loading a program.
