this should work like this regardless of any extra filter given (obviously
the filter should also be taken into account if set)
this seems hard - I wanted to make it do this also... I had a think about it
but I just couldn't see a simple way of doing it... how does the code
'know' one string belongs to another... I figurede it's impossible to do properly unless
you start searching/matching/analysing the tokenized code... which is when
I decided to do something different ;-)
interested to see where you go with this!
