I have attached the original patch (cleaned up with Uwe's original comments).

NOTE: this will not work but I am just sending it to help reconstruct the
thread.

I think to do this properly you would have to either A) create a new branch
without the topic specified B) work your way back through the dependencies and
reverse patch all those nodes which do not have a common ancestor with any of
your other dependencies.  As an aside I found that topgit does not like you
removing the only dependency left.  I was unable to get that to work at all.
I don't know why.

I believe you specified option A in a message after this one, correct?
