`Produce a reference' seems somewhat = ambiguous to me. But I can certainly
see what Nelson means:

   could line-break (and subsequently = page-break) between <word> and
   <index marker>, yielding an = erroneous index entry. It would therefore
   be highly advantageous to ensure that = <index marker> was always tied
   to the preceding <non-lwsp> = material. ** Phil.
