If you decide that you want to drop a patch, you can just merge in its
base with strategy "theirs". Then you have base=topic and so no .top*
files any more. This patch fixes tg summary and the helper function
recurse_deps() to handle these annihilated branches as if they don't
exist and don't show up in .topdeps files.
