Comment(by embray):

 I see what you're saying; I didn't realize that numpy ''should'' work with
 --editable.

 The reason this patch would ''not'' work with --editable is that it relies
 on `--egg-base pip-egg-info` being in `sys.argv` to determine that the
 egg_info argument is being run by pip.  However, that argument is not
 present when installing with --editable.  I don't think we can rely on
 looking up the frame stack since pip runs the setup.py in a subprocess.

 However, I tried removing the test for pip-egg-info and instead just
 fixing up `__file__` regardless of whether we're being installed by pip,
 and that seems to work just fine, including with --editable.
