[development] problems with db_rewrite_sql()

[Stella Power]

Hi,

I'm trying to implement db_rewrite_sql() on all sql queries that list nodes
in the faq module so as to support i18n localization. However, I've run
into difficulty getting it to work in a settings form.  The same code in a
different function works fine, so I'm unsure why the sql isn't getting
rewritten in this case.  I created an issue about it (#138624) a few weeks ago
but it hasn't gotten any replies.  

At this stage, this is the only issue preventing me from doing a new release 
of the faq module.  So if anyone has encountered this before or knows what I 
may be doing wrong, please let me know!

Cheers,
Stella
