[PATCH v3 6/9] t5520: test --rebase with multiple branches

Message-ID: <1431508136-15313-7-git-send-email-pyokagan@gmail.com>
In-Reply-To: <1431508136-15313-1-git-send-email-pyokagan@gmail.com>

Since rebasing on top of multiple upstream branches does not make sense, since 51b2ead (disallow providing multiple upstream branches to rebase, pull --rebase, 2009-02-18), git-pull explicitly disallowed specifying multiple branches in the rebase case.

Implement tests to ensure that git-pull fails and prints out the user-friendly error message in such a case.
