Shouldn't you use test_must_fail instead? From t/test-lib.sh
(paraphrasing):

  Writing this as "! git rebase master" is wrong, because
  the failure could be due to a segv.  We want a controlled failure.

It would be more readable to split this line on '|', i.e.:

+test_expect_success 'rebase against master twice' '
+	git rebase master 2>&1 |
+	grep "Current branch my-topic-branch is up to date\\."
+'

I think we prefer to save output to a file, and compare this file with
expected output (using test_cmp).  Additionally you can check if the
message you want is in correct stream (is in STDERR, and STDOUT is
empty).

Same as above.

Errrr... what?  Why git-log and not git-cat-file?  Why grep twice?
Additionally you do not check here that author is unchanged, only that
is not destroyed.
