Perhaps having a file named something like:
.git_foreign_scm_empty_dir  or some shorter name.
With the contents of the fast importer empty directory info put in there; If any book keeping is needed.

It also looks like you strip out meta-data. perhaps a file like:

.git_foreign_scm_metadata
We could use the .git/config file format for storing the bookkeeping data.
