Like for boilerplate, don't mark a module as not working only because
the maintener was to lazy to implement tests.

This reverts commit 3c84980e.

They bring nothing of value (we never use import * anyway) and introduce
a maintenance burden.

The __all__ that I left might not be very useful either but at least
they are not a pain to maintain; they are also used by pyflakes in some
cases.
