Jade's RtfFOTBuilder

["Frank A. Christoph" <christo@xxxxxxxxxxxxxxxxxx>]

I've been looking at Jade's RTF backend recently and I discovered that the
RtfFOTBuilder class keeps, along with a few other stacks, a stack of page
formats (called pageFormatStack_).  But simple-page-sequences are always
top-level, so what's the point of this?  The start() and end() methods
include code of the form:

  if (!inSimplePageSequence_) {
    // push or pop the page format stack
  }

Under what conditions would you be formatting a flow object which is not
contained in a simple-page-sequence?  (...under RTF, of course --- I know it
can happen with HTML, for example.)  Furthermore, if you're not in a
simple-page-sequence, shouldn't the page format stack be empty?
