That is pretty good!  Thanks.

I was still interested in indexing @itemx', so I tried:

  @table @code
  @vindex ABC
  @item ABC
  @vindex DEF
  @itemx DEF
  @end table

... which produced:

  <dl class="table">
  <dt><a class="index-entry-id" id="index-ABC"></a>
  <code class="code">ABC</code></dt>
    <dd><a class="index-entry-id" id="index-DEF"></a>
  <dt><code class="code">DEF</code></dt>

(double indentation used as emphasis) without handling @itemx it'd seem.

It looks like gather_previous_items supports @itemx (at least in the
Non-XS parser), so I might be able to figure that out tomorrow, sadly, I
am out of time for the day.  Hopefully, it wouldn't be too hard to
recover the anchors too (people have taken to like them a lot :) ).

Thanks again, this is already wonderful, have a great night.
