[GreenKeys] AP - Unshift on space?

[sdaitch at mor.ibb.gov]

I've never looked at the M-15 manual to see what was involved in the unshift on space, so I will have to accept the one part addition.  All I can say is I never saw a M-15 with the option.

The AP was using M-15 machines (and M-20s fpr that matter), at least in North Carolina, into 1979.  I know, I worked on them.  None of the machines I ever saw had them.  But I left the AP in early 1979, and I don't know when the last M-15 was retired in NC.  

I can only guess the AP didn't want anything else in the machine to interrupt service with a parts failure, if they could do so by eliminating the function.
