rebase: allow destination-free continue and abort (
issue5513)
rebase: test to show brokenness with requiredest
As shown in
issue5513, --continue is broken when destination is required. This
adds a patch that demonstates this silly behavior, which will be fixed in a
future patch.
rebase: move destination test to new test file
We'll be adding a lot more tests here, so it makes sense to have this in its
own file now.
