t5520: test --rebase with multiple branches

pyokagan · gitster · commit 9570d67c00d6 · 2015-05-29T09:15:24.000-07:00
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.
