In some cases, like the sub/super-project filtering attempted in this series, it may be necessary to carry over the mappings from one or more filter-branch run to another.
As the first part to this, make a --dump-map option that dumps a flat text file with lines of the form
$sha1 $(map $sha1)
after it has established all mappings.
