a working copy parent. We should be moved back to the starting commit as usual
even though it is hidden (until we're moved there).

Divergence cases due to obsolete changesets
-------------------------------------------

We should ignore branches with unstable changesets when they are based on an
obsolete changeset which successor is in rebase set.

Changeset d and its descendants are excluded to avoid divergence of d, which
would occur because the successor of d (d') is also in rebaseset. As a
consequence f (descendant of d) is left behind.

If the rebase set has an obsolete (d) with a successor (d') outside the rebase
set and none in destination, we still get the divergence warning.
By allowing divergence, we can perform the rebase.
