This seems to be in principle the same as the tie branches. It might make sense to have a way to _optionally_ make a tie branch.

How should that work? Maybe there needs to be even an explicit support for this - should TopGit just check the dependency tree when sequencing the topic branches and have a step that says:

	"I'm going to sequence branch A. If there is branch T that has
	only already sequenced branches + branch A as dependencies,
	use T's content instead of A."

Would that be satisfactory?

Finding out this information would be very expensive, of course. But for other reasons, we might want to keep a cache of branch dependencies.

Of course, in the case of

        A1--A2--A3--A4--C
                       /
        B1--B2--B3--B4.

the sequenced branches would still be like

        A1--A2--A3--A4--B1--B2--B3--C

unless you create the T1..T4 branches manually.
