This is testing the behaviour of the goto-inspect binary in case a binary
15+
is present, but no inspection option is present.
16+
17+
This is labelled `winbug` to avoid running on windows because of issues with
18+
the empty string in line 3 (simulating the lack of an option) not working as
19+
it should (it is contrary to the behaviour of unix systems). The behaviour
20+
has been verified manually on a machine as working as expected, but getting
21+
the test to run automatically is a lot more involved, so we're opting to
22+
skipping this on that platform for now.
