The review command allows the patch set to be specified by the commit's sha1 revision. It is possible that the revision does not identify a unique change if the same sha1 has been pushed to more than one project or to more than one branch of the same project. This causes the review to fail with an error. The results can be narrowed down to a specific project by using the --project option, but it will still fail if the sha1 is on more than one branch in the same project. Add a new --branch option that allows to narrow down the results by branch. Bug: Issue 1752 Change-Id: I555dc9de1b092e7562f5d99c4c60df589935a47f
