Ping: [PATCH+wwwdocs 0/8] A small Texinfo refinement

Ping on this patch.  I took the liberty to rebase it.  The changes are
minimal, so I didn't want to resend the entire patchset.  I included a
range diff and a pull request for your convenience.

The render is also updated, and ``make all && make html'' passes (which
is something I forgot to check last time, so tm.texi had some
complaints, apologies).
