"remote_url" and "remote_browser" parameters for "./go test_remote".

E.g.
./go test_remote remote_url=http://1.2.3.4:1234/wd/hub remote_browser=ie

I found no way to make this work without a change.
Including
./go test_foo jvmargs="-Da=a -Db=b"
which doesn't set both properties a=a and b=b and doesn't work at all: a space in jvmargs messes everything up.
