Improve the PI autobreaks="yes". Currently, it seems to be "yes" by default but has no effect. It should prevent a page break from appearing in

• the middle of a figure (see Figure 1 in the attached file)
• in the middle of a reference (see Section 10.2 in the attached file)
• between a section title and the first sentence (see Section 5 in the attached file). This is the same as section title as last item on the page #72, which is marked fixed, but doesn't seem to be for this case.

If there is an Appendix A, insert a page break before it. (This could be tied to rfcedstyle="yes", as it's RFC Editor style.)
Or, improve the ability to insert a page break -- vspace blankLines="100" doesn't always work.

This also applies to texttable. Page breaks appear in the middle of tables in the output from the file for #173. As reported to the list by Y. Weingarten.

Massive fixes in 1098.

While a couple of pieces are left to do (break on first appendix), the code now produces the same essential output for both the nroff and the text versions in terms of pagination for the regression test cases.

More fixes now exist as well.

vspace of greater than 51 will force a page break anyplace it occurs
We now break on the the first appendix if the rfcedstyle is 'yes'

There were some issues where break hints were being over written by smaller (or worse) hints. These have now been cleaned up so that they don't occur in the nroff output anymore.
