I checked an old archive and nothing seems to be changed. This is rather
old code btw.

The \index command has always eaten up spaces and pars. This means that in

\section{Did you know that Berend}

\index{de Boer}

is a clever programmer. 

the \index write node will not interfere and the index indeed is attached
to the right location. 

Also think of:

bla \index{well} theindexbelongstothisword 

where the long work ends up on the next page. So: 

abc \index{def} ghi == abc \index{def}ghi

with the following alternative: 

\def\complexdoregister[#1]#2% just an example, this code will not be used 
  {\doprocesspageregister[#1]{#2}%
   \ifvmode\nobreak\expandafter\GotoPar\fi}

the space is obeyed but I prefer the method where the index *precedes* the
word since it's more secure.
