l2hinit.perl version of the function (which
overrode a version in latex2html), but
do_cmd_index() was overridden. Since
do_cmd_index() was the only caller, we can trash
this.
define_indexing_macro(): New function used during setup to support
more dynamic dispatch for indexing.
process_index_macros(): New function; implement dynamic dispatching
of indexing support functions, allowing many
targets used in indexing to be shared by
multiple index entries. I.e., something like
\index{foo}\bifuncindex{bar} can now share a
single target anchor.
These indexing changes reduce the amount of clutter in the generated
HTML files. In the reference manual, this cuts the number of targets
by 44%. Targets are less affected when generated by environments
rather than macros.
