Not principally.  At least nothing we should care about initially.

I didn't care about `pos-visible-in-window-p' in this example.

I didn't write that loop (IIRC Kenichi Handa wrote it).  The sheer
presence of it however seems to indicate that `pos-visible-in-window-p'
might have given an off-by-one-line answer when `point' is on the last
line of a window, at least back in 2000.  Maybe this a non-issue now.
