Seems to print what is needed. Now, just embed it in sh script. A
program in C could be longer, and required a compiler.

An obvious
approach, which would leave no real traces in documentation, would be:
$ awk '{print NR, $0}'
A more precise emulation would be more of a pain to type:
$ awk '{printf("%6d\t%s\n", NR, $0)}'
but perfectly usable in a script.
Yes, but awk wasn't widely available until 7th edition. I imagine work
on it began before `num` in 2BSD, but few outside of Bell Labs would
have seen it prior to 1978 or so.
I wonder if the use-case was just sufficiently rare that no one felt like
building a special tool and it was just done on an ad-hoc basis, if
necessary.
