Grouping the commands for redirection via a "{...}>expect" block is
less noisy than redirecting each command separately, thus more
reviewer-friendly. And, {...} blocks are used regularly in the test
suite, so no issue there.

I do agree that a single git-rev-parse with all 5 arguments makes more
sense (and would be appreciated by Windows folk). Also, the 'printf'
could be replaced by a simple 'echo' if we want to get nit-picky.

Finally, a style nit: We don't normally indent the content of a
here-doc like that. Instead, the content is normally aligned with the
closing EOF, not indented beyond it.

Please use rev-parse only once.

I am not sure about the usage of { braces } in the test suite,
+cc Eric who sent a test suite linting series recently.
Do we need to em-'brace' the statements that describe the
expected behavior? (Or is it supposed to be easier to read
for the reviewers? I found these very readable so far... but
this question just came up)

Thanks,
