So, to me, this change actually makes sense!

Agreed!

I can look at this this weekend. Adding a HAL pin for rapid override should be 
no problem. Tying that pin to halui should make it work as before for those who 
want it that way.

 I have a Mori Seiki CNC lathe with Fanuc 0i-TC control and
 a Haas TM-1 CNC mill.  They both have independent control
 of feed override and rapids override.  I would not expect or
 want feed override to control rapids or vice-versa.  I guess
 I can see some logic in the max-velocity approach, but it is
 different than the other CNC's I use.

I can see the utility of a rapid-override pin, in addition to the
feed-override and max-velocity pins we currently have.

The addition of rapid-override would make it easy to implement the
behavior that Mark Tucker desires.

I would be happy to review a patch against master that adds this pin.
