The fundamental difference is that with a numeric prefix ^F/^B
scroll by screens, and ^D/^U scroll by lines.  It's only if there
is no numeric prefix that ^D/^U default to scrolling by half a
screen.  tog(1) does not support numeric prefixes.

I also think it's questionable to use 'd' and 'u' as synonyms for
^D and ^U.  This is limited to less(1) and not present in vi(1),
and we may want to reserve these keys for future functionality.

Personally, I have no use for ^D/^U.  I'm not opposed to adding it
with "scroll half-screen" semantics, though.
