$STRIP_INDEX_TT:  New flag.  If set, the <tt>...</tt> around stuff in the index

"""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

Note that an item which matches the format of a collapsable item but which
