[begin sarcasm] I am truly awed at the magnitude of the resource saving here.
Clearly saving 190 milliseconds of CPU time, and about half a second of real
time, on a command used a few dozen times a day is of enormous importance.
[end sarcasm]
We didn't think savings of this magnitude worthwhile on our poor struggling
old pdp11/44, never mind on a modern machine. Not when it added substantial
programming and maintenance overhead forevermore.
