There are a number of things not present in "normal" imports that we
nevertheless support and need to be tested:
* broken timezone adjustment (+051800->+0261; observed in the wild
in real repos, and adjustment prevents fast-import from dying)
* commits missing an author (observed in the wild in a real repo;
just sets author to committer)
* optional additional linefeeds in the input allowed by
git-fast-import but usually not written by git-fast-export
* progress and checkpoint objects
* progress, checkpoint, and 'everything' callbacks

Python wants filenames with underscores instead of hyphens and with a
.py extension. We really want the main file named git-filter-repo, but
we can add a git_filter_repo.py symlink. Doing so dramatically
simplifies the steps needed to import it as a library in external python
scripts.
