OK. You can write 'EOF' in the shell, too, but we tend not to in this
project (and you can write \EOF in perl, but I agree that it is much
less common in perl code I have seen).

Looking at it again, it is actually quite subtle what is going on. We
wrap the outer test_expect_* calls in double-quotes so that the inner
ones can use single-quotes easily. But that means that technically the
contents of the here-doc _are_ interpolated. But not at test run-time,
but rather at the call to test_expect_*. And that is why we nee to use
"\\" instead of "\". So I think anybody trying to tweak these tests
using shell metacharacters is in for a surprise either way. I'm not sure
it is worth worrying about, though, as handling it would probably make
the existing tests less readable.

OK. :)

Good catch. I didn't notice that, but it definitely makes sense to reuse

It all looks sane to me. Thanks again.
