This seems to make the previous PR for redirection redundant as tee -quiet does the same.

I know its a bit odd but what happens with tee -file foo { report_checks > bar }?

@maliberty yes, this provides a consistent interface to use.

I don't think we want to support that, so it should throw an error.

[maliberty]

should throw an error.

Does it?

[gadfort]

Does it?

It does now.

I also added the variable redirect to round out the options (since I use it in a few places via with_output_to_variable).
