The 'k' was fixing downward movement of $ command. After replacing with
normal! $, it works without that fix.

That doesn't work for me, using vim 7.3 (even after adding the ')').
However, I prefer the function version because it's more readable.

I see, but <c-u> seems like a pretty bad kludge. I remember using it at
least a couple of times before, and I still did not remember it because
it's pretty counter-intuitive. I think it would be better if there was
an arg to *map to turn it off, like <no-prepend-range>, because users
would look into *map arguments help for explanation of this behaviour.

That doesn't seem reasonable, why should Vim assume the count applies to
the first (of possibly dozens) normal command in a function?

Is this sort of questions ok to bring up on vim-use list?

Anyway, thanks a ton for your help and here's what I ended up with if
anyone wants to use this too:

func! EndOfLine()
" Go to Nth char before end of line
normal! $
if v:count | exe "normal ".v:count."h" | endif
endfu
nnoremap $ :<c-u>call EndOfLine()<cr>
