Definitely. I see your point now. This must be a definite bug in 
in_path().

One problem though is that when in_path() traverses the tree upwards, and 
encounters a directory which it can't read it can't complete its job. On 
the other hand, it shouldn't have to do that, it really only needs to see 
that the output file is not below the top level of the input tree. Or am I 
missing a case here?
