These test cases focus only on testing the parsing of refs on stdin,
without bothering with the rest of the fetch-pack machinery. We pass in
the refs using different combinations of command line and stdin and then
we watch fetch-pack's stdout to see whether it prints all the refs we
specified and in the same order as we specified them.
For the --stateless-rpc tests we cannot easily execute fetch-pack to the
end because that would require simulating the remote protocol. We settle
for only checking 2 cases:
1) Whether fetch-pack correctly fails to parse the refs if they are not
terminated by a flush packet
2) Whether fetch-pack finishes parsing the refs without error when they
are correctly terminated by a flush packet
The fetch-pack invocation fails in both cases due to the missing remote
side of the protocol, but it fails in different ways which allows us to
determine how the refs parsing ended by inspecting the different error
messages.
