We found a few run-away here documents that are started with an
end-of-here-doc marker that is incorrectly spelled, e.g.
git some command >actual &&
cat <<EOF >expect
...
EOF &&
test_cmp expect actual
which ends up slurping the entire remainder of the script as if it
were the data. Often the command that gets misused like this exits
without failure (e.g. "cat" in the above example), which makes the
command appear to work, without eve executing the remainder of the
test.
Piggy-back on the test that catches &&-chain breakage to detect this
case as well.

* The previous one was simply buggy; I forgot that there was an
interesting redirection going on inside test_eval_. Sorry for
the noise.
Also we could do this in the same test_eval_ without adding
another one, which is how this version does it.
