@afourpaper is in the same class of commands as @smallbook itself. So in
theory @cropmarks could be used with @afivepaper and then you would want a way
to say whether it is being printed on A4 paper or letter size paper or
whatever.

This change moves the printed page further down the page to how it was
originally.

I'm not sure but it may have been the change for this log entry:

1998-11-11  Andreas Schwab  <address@hidden>

        * doc/texinfo.tex (\onepageout): Put the cropmarks in vboxes of
        zero height so that they don't contribute space themselves.
        Compensate for \topandbottommargin.
        (\internalpagesizes): Advance \outervsize by 2\topandbottommargin,
        not only 0.6in.

Clearly it's not a feature that anybody uses.  Can we just remove the feature
and revisit it if somebody is actually going to use it for printing a book?
