Cwm parses from stdout before handling command line arguments. This  
is counterintuitive, and I will accept as a bug.

Your shell was telling you that you were in /tmp. However, cwm had no  
way to know that --- the OS was telling it the true path when it ran  
a pwd. The bug is way upstream from cwm, and it is unlikely we can  
fix it. I too am on OS X .

30-6-160:~ yosi$ cd /tmp/
30-6-160:/tmp yosi$ type pwd
pwd is a shell builtin
30-6-160:/tmp yosi$ /bin/pwd
/private/tmp
30-6-160:/tmp yosi$ pwd
/tmp
30-6-160:/tmp yosi$
