cwm (bug?): strange behaviour with --filter argument

Hi,

While starting to learn N3, I came upon this strange behaviour of the 
--filter command line option. If I execute it like:

python /home/mbranco/2000/10/swap/cwm.py /home/mbranco/tmp4/test1.n3 
/home/mbranco/tmp4/test1_files.n3 --think 
--filter=/home/mbranco/tmp4/test1_filter.n3

...or like...

python /home/mbranco/2000/10/swap/cwm.py /home/mbranco/tmp4/test1.n3 
/home/mbranco/tmp4/test1_files.n3 --think --filter=/tmp/test1_filter.n3

...it doesn't give the same results.
The only change between those two is the path of the 'filter' file. It 
appears as if the 'filter' file is not in the same path as the others, 
the command doesn't work properly... Still, the results should be the 
same, no? I'll probably go through the source code myself to see if I'm 
missing something, but I've decided to send you this report anyway.


Thanks in advance,
Miguel Branco

PS: I've included as an attachment the sample n3 files I tested.. I'm 
using cwm checked out from CVS a couple of days ago. Also... I really 
enjoy this N3 thing :)
