runtests.py -coverage

Lack of coverage quite often means bugs (and usually trivial bugs, so
improving coverage gives good payoff for little work).

Some modules are reported to have lower coverage than in reality because
they contain gmpy/non-gmpy-specific code. It should be easy to write some
tests that always test the non-gmpy code when in gmpy mode.

Some other code is only meant to be run interactively, but could still be
tested (e.g. for "verbose=True" code by temporarily redirecting stdout to
stringio).

Also, some code reported as uncovered here is already covered by doctests.
Nevertheless, near-100% coverage by runtests.py should be possible with a
little work.

Nice work!

When did you run the doctests the last time? I suspect many of them are broken.

A couple of days ago.

Running them now, all module tests pass. There are some failures in the .txt docs due
to the change of mpi.__repr__.
