Commit dec4b73aa0 ("Allow `brew update --rebase`") changed the format of
the `git pull` command slightly, introducing an extra space (to allow
for the --rebase option), so let's update the test expectations for this.
We still need to write tests for '--rebase', but in the meantime they
once again pass for the normal case.
