The HTML for the second-layer TOC is missing after applying this
patch, so the CSS is not broken, just the HTML.  div#tocframe is still
generated, but only for the top-level TOC.

Also, it's only an accident that this would make the webpage
navigation more comfortable, since the real solution is to remove the
anchors from the hyperlink URLs when the texinfo is split by section
(I'm working on it).  With this patch, the hyperlink anchors point to
a non-existent anchors; while harmless, it's still annoying.  :-)
