[PD] get patch path

[Patco]

I tried the python os.getcwd() function but it outputs path names with 
'////' instead of '/'.
 (Anyway the py external has problems i don't understand right now,
 it works when i run it with double-clicking on the patch but give me 
'AttributeErrors' when I open the patch or create the py object from pd 
on win32).

Is there another solution for getting the path of a patch or at least 
the working directory's path?
