Using convert_os_errors to convert errno.ENAMETOOLONG to PathError results in unexpected keyword arguement 'exc' error. Seems that this line will set exc=exc_value however PathError does not take in exc parameter.

The following example code:

import errno from fs.error_tools import convert_os_errors from fs import errors as fserrors try:	from fs import open_fs	f = open_fs('/tmp')	f.open('x'*500, mode='w') except OSError as e: with convert_os_errors("foo", "test"): raise e 

results in: TypeError: init() got an unexpected keyword argument 'exc'
