Re: Scrolling doc bugs misnaming of scroll-up-conservatively

[Richard Stallman]

    Wait a minute....  I know this is all confusing, because the key
    labeled "Page Up" is bound to scroll-down and vice versa, but if we
    take emacs on its own terms, then "when a window scrolls up because
    point is above the window start" doesn't make sense, does it?

The explanations in the Lisp manual were accurate because the meanings
of the two variables were backwards!  scroll-up-aggressively was
controlling scrolling downward and was documented as such.

I fixed the code, and updated the documentation to match.  Thanks.

    Also, the interaction of the aggressive and conservative scrolling
    variables needs to be documented, i.e. which takes priority?

    It appears that, because of the high potential for confusion about
    which way is up, most of the descriptions in this node are careful to
    say "scrolls the text" rather than "scrolls the window".  Two
    exceptions to this rule that should be fixed are in the descriptions
    of scroll-margin and recenter.

I clarified that too.
