For the record, "$" does take a count, going to the end of the line
count-1 lines down. With only the single line, there's no count+1
line to go to, so both (n)vi and vim rightfully errors at you.

:help $

With more than one line you can observe the expected behavior. I'd
use "$" with a count more often if it did "count" lines rather than
"count-1" lines, because "count-1" requires doing the math in my
head. Just a little friction.

"^" doesn't take a count, so both (n)vi (at least here on FreeBSD &
OpenBSD) and vim ignore attempts to provide a count. I could see it
going either way here -- either erroring or just ignoring it.

There are some small "e" implementation differences between vi and
vim as detailed in `:help WORD` (right above `:help object-motions`)
but I don't think you're hitting this known case. I was surprised to
see that this nuance you encountered wasn't documented (as best I can
tell).
