On the `distributedmigration` branch I have `git-annex migrate` recording
migrations on the git-annex branch.
Its method of grafting in 2 trees, one with the old keys and one with the
new is quite efficient. In a migration of 1000 files from SHA256E to SHA1,
the git objects only needs 52kb to record the migration trees.
Compared with 424 kb needed to update the location logs.
The total git repo grew from 508kb to 984k.
Next up: Make `git-annex migrate --update` find new migrations started
elsewhere and apply them to the local annex objects.
