As far as I can tell from looking at the code, the which function is
ultimately looking through the load path and once it finds the file,
it concatenates the directory where the file is found with the file,
separated by filesep.  So what does

  path

print on the Windows system?  I'd guess it includes

  c:/octave/mataa/mataa_tools

I'm not sure why forward slashes are used here instead of filesep.
How was that directory added to the path?
