t9902: verify that completion does not print anything
The Bash completion script must not print anything to either stdout or stderr. Instead, it is only expected to populate certain variables. Tighten our `test_completion ()` test helper to verify this requirement. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
