Subject: html doc: "collapse all" shouldn't hide whole TOC.
* genman.txr: show the toggle as "expand all" initially.
Assign the sections of the TOC to the "tocsec" class,
and then select the elements by class rather than by the
dl element type. This avoids selecting the dl that wraps
the entire TOC.
(xpanded): New boolean variable.
(toggleall): Base toggle on boolean variable rather than
the state of the first section dl element.
Toggle the xpanded variable.
