Well, the doc strings for these commands don't really describe
interactive usage at all, but I think most people would interpret what's
there as "it's like (interactive "p"), but with no prefix at all it
behaves differently". (Which is what it does -- a full screen instead
of a line.)
Stating this explicitly in the doc strings of these four commands would
be nice. So something like:
Interactively, giving this command a numerical prefix will scroll by
that many lines. Without a prefix, scroll by a full screen.
