AIUI technically what it does (without --squash) is take the tree-sha
of the tree (the datastructure which is the git equivalent to a
directory) pointed to by an upstream commit (perhaps/probably one on a
branch) and grafts it in directly as an entry in a sub-tree (i.e. a
subdirectory) of the tree of the downstream repo.
