I know that the patch you wrote is not good.  However, it is a good
starting point.

We need to consider cases where the branch we are merging with is an
ancestor or an descendant of HEAD.  The patch only take descendants
into account.  There may also be more than one branch we are merging
with.  All these cases must be considered.  In the case of an octopus, the
cases are slightly more complicated.

I have a patch that work for all cases except for some octopus cases.  I
have written a few test case.  All existing tests succeeds.

I will not be able to work on this for a few days, but I expect to have a
working patch some time this weekend.

I have not looked at the documentation but assume it should not be to
hard to add some documentation as well.
