DOCBOOK-APPS: DocBook XSL Stylesheets V1.50.0 extra top margin

[Elliotte Rusty Harold <elharo@metalab.unc.edu>]

I've noticed that the 1.5 XSL-FO stylesheets add about an extra inch
of white space between the chapter number at the top of the page and
the start of the first body text on the page. Thus a chapter that was
40 pages with the 1.4.8 stylesheets, rendered by FOP 0.20.3-RC1, is
now 46 pages. Has anyone else noticed this new behavior?
