white space and intervening indexterm elements

[Cheryl Chase <cheryl@isna.org>]

Arggh. I've completed the index for my book, by using Oxygen (an xml  
editor) to insert indexterm elements very close to the references I  
want to index.

Now I realize that this has caused my pdf to have two spaces between  
words, where there should only be one, when there is an intervening  
indexterm.

Here's a snippet of the docbook source and the corresponding fo. xep  
(Version 4.4 build 20050822) produces a pdf that has two spaces  
between "12th week," and "testosterone".

How best to repair this?
