  I think that would be possible to do, too. ;-) It really depends on
how general your patch tree is - what we can't make to work is just the
most generic case, but e.g. if master is a *leaf* branch nothing else
depends on and it can't get the branch through multiple paths, you can
do the dependency removal rather easily (if it can get through multiple
paths, you can still do it but you might have to deal with big
conflicts).

  But if you scenario indeed is totally generic, I'm afraid I don't know
how to make TopGit remove dependencies, except perhaps for the price of
massive complexity and massive slowdown (pretty much redoing all the
history walking etc.). Maybe someone else comes by with a genial
solution...
