$STRIP_INDEX_TT:  New flag.  If set, the <tt>...</tt> around stuff in the index
	is dropped.  This is more O'Reilly-like.

&make_str_index_entry:  Honor $STRIP_INDEX_TT.

&make_mod_index_entry:  Honor $STRIP_INDEX_TT.

"""Combine similar index entries into an entry and subentries.

For example:

  \item {foobar} (in module flotz), 23
  \item {foobar} (in module whackit), 4323

becomes

  \item {foobar}
    \subitem in module flotz, 23
    \subitem in module whackit, 4323

Note that an item which matches the format of a collapsable item but which
isn't part of a group of similar items is not modified.

This results in a much more readable index, with less repitition of text;

(RFC references were formatted three different ways.)

\idxcode{}:  New macro; used to mark things that would be \code{} for entry
	into the index.  This allows easily switching things around for the
	font used in the index.  (O'Reilly seems to keep it all plain roman

(1) Explicitly clear __builtin__._ and sys.{last,exc}_* before
clearing anything else.  These are common places where user values
hide and people complain when their destructors fail.  Since the
modules containing them are deleted *last* of all, they would come too
late in the normal destruction order.  Sigh.

(2) Add some debugging aid to cleanup (after a suggestion by Marc
Lemburg) -- print the names of the modules being cleaned, and (when
-vv is used) print the names of the variables being cleared.
