The split command will create a new repository for all files foo in a

The replant command reverses that process, re-adding the path prefix
for each file. It may be possible to extend that process into one that
automatically reintegrates the new commits in the original history,
but I never had time to complete that work.
I did originally add the "replant" functionality into my version of
the git-subtree script, but given the number of commits in the
original repository, git-subtree turned out to be inefficient, due to
the use of temporary files (tens of thousands of files IIRC).
Those problems led to my development of git-splitter in Python
(bypassing the problem of temporary files), but just including the
functionality I needed, join was not one of those functions.
That still doesn't answer the question: why did you need to write a new
tool instead of extending git-subtree?
The primary problem with git-subtree was that I ended up with a temporary
file directory containing 100+K files, which I tracked back to being used
to manage the commit-to-tree mapping. On Windows, at least, that literally
slowed down the process to a crawl.
If one doesn't use "replant", is your tool different from git-subtree?
No, it is not different. However, my tool will use RAM, not diskspace to
manage information.
