Create test to ensure this behavior happens. There are some cases that currently don't pass. The first case is where a feature and master have diverged, running "git rebase master... master" causes a full rebase to happen even though a fast-forward should happen. The second case is when we are doing "git rebase --fork-point" and a fork-point commit is found. Once again, a full rebase happens even though a fast-forward should happen. Mark these cases as failure so we can fix it later.
