Instead of filtering non-merge commits I would suggest doing git rebase on the
latest revision of the old git repo. That way you will get a set of commits
that should apply cleanly. The reason it is failing now is that it is
impossible for git am to do a 3-way merge without the original git objects,
which are obviously not available in the new repo.
