I was actually thinking to only generate the master bookmark for
`test_revision_arg` and leave everything else as is. It seems like it would be
simpler than generating two websites. Or if you want to run all the tests on
both, maybe we could just use parametrize somehow?

I am not sure how this would work then. The thing is that want to test that the
generation is done with the expected, provided revision. So unless we only
wanted to test that the argparse code works then wouldn't we have to generate
two sites to ensure they are not from the same revision/bookmark and to test
this wouldn't we need to add a file or some other change in the generated site?

Perhaps I am misunderstanding how you want to test the behavior.

As discussed over Mumble we agree this bit of duplication in tests and
everything is not needed. Instead I will alter this method to accept a new
parametrized fixture called 'revision' which returns None, and 'master' then
based on this value we can assert the expected outputs.
