The GNUstep implementation of -[NSFileManager
createDirectoryAtPath:attributes:] creates intermediate directories in the
path if they don't exist; e.g. if called on @"/tmp/foo/bar/baz" it will create
directories "foo" and "bar" if they don't exist, instead of failing.

This contradicts the documented and actual behavior of Apple's implementation
in the Foundation framework. The docs for that method state "The directory to
be created must not yet exist, but its parent directory must exist." I know
from experience that this is the actual behavior.

A fringe benefit of fixing this is that the implementation of the method looks
like it will get a lot simpler :)

A side effect is that -[NSFileManager createDirectoryAtPath:
withIntermediateDirectories: attributes: error:] will create intermediate
directories even if the corresponding parameter is NO, because it in that case
it calls into the older version of the method.
