The && needs to go on the first line, not the last line of the here-doc.
However, that was not my main concern in the previous review. What
disturbed me was that the new tests, which were supposed to be
checking if "-" behaved as @{-1}, were succeeding even without patch
1/2 applied which implemented the "-" alias for @{-1}. That seems
wrong. I don't think you particularly addressed that issue in this
version (even though the first couple tests will now fail without 1/2
due to the changed error message).

Reminder: Wrap commentary to about column 72, as you would the commit
message. (I re-wrapped it manually to reply to it.)

Considering that the test titles already tell us the intent of the
tests, I don't find that the directory name "no_previous" adds much
value to tests checking the behavior of "-" with no previous branch. A
single, consistent name used throughout all these tests would be less
surprising and place smaller cognitive load on the reader.

Style: Unnecessary extra blank line.

Place the && at the end of this line. Also, prefix EOF with a
backslash to indicate that you don't intend any interpolation to occur
within the here-doc. So:
cat >expect <<-\EOF &&
Ditto for the remaining tests.
