t3432: test rebase fast-forward behavior
When rebase is run on a branch that can be fast-forwarded, this should
automatically be done. 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.
