Subject: [PATCH] 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.
