Description of problem:
When I create a book and include indexes where the <indexterm>s are used to define a startofrange and endofrange, the index entry should look like this:

Subject start-end

For example:

Publican tools 101-125


Instead the output generated is like the following:

Subject start-end, end

For example:

Publican tools 101-125, 125



Version-Release number of selected component (if applicable):
Seen in Publican 2.8 on Fedora 16 64 bit. Probably affects other versions and OS versions.


How reproducible:
100%


Steps to Reproduce:
1. Create a document. At some point add an index tag as follows:

<index />


2. At the beginning of the document, add an indexterm tag as follows:

<indexterm class="startofrange" id="StartOfPTR">
<primary>Whatever</primary></indexterm>


3. At the end of the range, put this indexterm:

<indexterm class="endofrange" startref="StartOfPTR">
<primary>Whatever</primary></indexterm>


4. Build a pdf document.

 
Actual results:
When the index is generated, you get something like:

Whatever 10-22, 22

The last page in the range - 22 - has been duplicated.



Expected results:
When the index is generated, you should get this:

Whatever 10-22



Additional info:
None.
