I think there is a bug in the code, coming from the fact that
{{{
sage: Integer(None)==None
False
}}}
You also should have test cases (doctests) for all the different
combinations of start/stop, and test them, too. You know that you can run
Sage so that it tests doctests in a particular file, right?
E.g. the bug above would have been caught by the proper doctest.
Also, for some reason you removed the test {{{sage: v =
prime_powers(10)}}}, but it was there for good reason.
