I think this was brought up sometime ago, but I can't find it right
now.
I can never remember how to call run_testsuite() since all of the
arguments are optional, so order matters, and my most common usage is
to want to specify just a subset of the test suite.
Could we change run_testsuite to use a keyword style?
Something like
run_testsuite(display=<t/f>, known_bugs=<t/f>, tests=<list of tests>)
The keyword args can come in any order.
The default for run_testsuite() remains the same. Only if you want to
specify something different will you see a change.
