Richgo testfilter will not create build for failing tests

[eloo]

Hi,

i'm trying to use richgo together with go-junit-report and use your recommendation but there is drawback i have found.
With the command

go test ./... | tee >(richgo testfilter) | go-junit-report

your build will not fail (return status == 0).
This is bit weird as with this step we don't have the option to stop build broken packages..

So far i have the following workaround

go test ./... | tee >(richgo testfilter) | go-junit-report; exit "$${PIPESTATUS[0]}"

Maybe this can be added to the docs?

I don't have the confidence to describe them.
I'm waiting your pull-request.
