pdf documentation broken

[Graham Percival]

I broken the creation of the pdf docs; I suspect it was the @cindex 
@code{} => @funindex macro (producing @findex and @kindex) change.  I 
didn't notice it at the time (a few days ago) because it didn't 
complain for some reason.  (enough pre-built stuff lying around in 
out-www/ , perhaps?)

The HTML docs are fine; the problem occurs with texi2dvi.  In the log 
snippet below, it gets into an infinite loop and I kill it with ^C.  
I've tried commenting out the relevant section of tweaks.itely; when I 
do that, it fails on the first @funindex entry in basic-notation.itely. 
 Is there a maximum number of indices that texi2dvi can handle?  (a 
maximum number which is smaller than the max number that texinfo itself 
can handle?)  If so, can this limit be increased?
