Format question about "list" output page?

[Gordon Royle]

Hi,

I was just looking at the HTML generated by the "list" option and  
noticed that each line is represented thusly:

<tr>
<td align="right"><tt>2</td><td></tt></td> <td align="right"><tt>1</ 
tt></td> </tr>
<tr>
<td align="right"><tt>3</td><td></tt></td> <td align="right"><tt>2</ 
tt></td> </tr>



Each line consists of THREE <td> items

Item One; <td align="right"><tt>2</td>

Item Two: <td></tt></td

Item Three: <td align="right"><tt>1</tt></td>



The third item seems to be a correctly nested item   "open td, open  
tt, content, close tt, close td"

But the first and second items seem weird... the second item contains  
ONLY the "close tt" tag, and nothing else.


So this means that the td and tt tags are not properly nested, which  
means that the file is not valid HTML, which means that I cannot  
parse it using standard HTML parsers.....


Is there a reason for doing this?


Thanks

Gordon
