Oh yeah, I remember now.  OK guys, here's the problem: we've run
out of headings.  Texinfo supports
@heading   - used for sections
@subheading  - used for subsections
@subsubheading  - used for subsubsections

We need one more.  In NR 1+2, we need it for the portions of each
doc page: predefined, snippets, seealso, knownissues.

In the LM, we could use some headings to divide the pages, such as
4.1.4 Tweaking methods

In HTML, it looks iffy when the inside-page headings are as big as
the subsubsection headings, but it isn't absolutely terrible.  In
PDF, it looks much worse.

Any suggestions?  For HTML, we could use some CSS.  For PDF (and
info), I'm not certain what to do.

Cheers,
