Merge branch 'jc/test-parse-options-expect'
t0040 had too many unnecessary repetitions in its test data. Teach test-parse-options program so that a caller can tell what it expects in its output, so that these repetitions can be cleaned up. * jc/test-parse-options-expect: t0040: convert a few tests to use test-parse-options --expect t0040: remove unused test helpers test-parse-options: --expect=<string> option to simplify tests test-parse-options: fix output when callback option fails
