Thanks for the links!

Maybe this reserved space was needed when various vertical dimension
variables (top-margin, bottom-margin, etc.) were *scaled* depending on
the staff size.  But now since they are exact (in 2.11.58), maybe this
*reserved* space can be decreased or eliminated entirely?

I could be mixing up two different issues, I don't know.  But I'll
look at scm/layout-page-layout.scm to see if I can understand what is
going on.

Cheers,
