Problem:

Problem:
  Invalid HTML generated for manually created Indexes that lack
  Indexdivs.
Cause:
  The indexentry template assumes a dl wrapper has been generated,
  but the dl wrapper gets generated only if an Indexdiv exists.
Fix:
  For Indexes that lack Indexdiv, generate a dl wrapper before
  processing Indexentries (closes bug ##1196670; thanks to Petr
  Pajas for reporting the problem).
Affects:
  HTML output for manually created Indexes; has no effect on
  processing of automatically generated Indexes.
