This procedure is equivalent to editing all the content in the
subdirectory to match the contents of the specified treeish (optionally
adding it to the index), and Git has about as much awareness of what
you're doing as if you'd literally made all the changes by hand. It is
nothing like Subversion's selective subdirectory updating (where
revisions are tracked on a per-subdirectory basis), and suggesting that
it is will just court more confusion.
