Thanks for digging that out. I was confused at first, because 4.0 BSD
implemented it without arguments, while the above article tells
"When I added it to BSD, I made a conscious decision to permit
exactly one arg - not a general command line."
But the first regular occurence (active by default) in 4.2BSD
is implemented like that.
Do you feel like providing access to more of your research?
