I wonder if the CDC 6000 series console was an inspiration for that.  It had some fairly long commands, but it would autocomplete unconditionally, supplying the next character whenever there was only one possibility at that point in the string.

So the command "check point system." would require only "che", the software would supply the rest.  Oh yes, and whenever the command was complete (CR allowed at this point) the display would "ripple intensify", brightening every 4th character in a ripple pattern.

All this was in NOS 1 and I'm pretty sure goes back a ways further, so to early 1970s if not earlier.
