Right, what is better to not have?
`line-number-at-pos' or `save-excursion'?
Normally, I'd say `save-excursion' is better to
not have than most other functions. But here,
`line-number-at-pos' is implemented with
`save-excursion'! But at least it doesn't

Indeed, I thought about it this, but the code
sure looks cryptic, especially for such
a trivial task. Again, this won't show when
"point-at-final-line" is called!
