Feature request - Subtree checkouts

Heya,

I'm trying to dig at various issues that are potential holdups for migrating the Gentoo CVS tree into Git.

Since shallow checkouts are now available, there's just one more thing that's missing: subtree checkouts. Not to be confused with sub-projects.

If the master tree has this as some example contents: /foo /abc/... /bar/example /bar/baz/some-content

We need to be able to check out arbitrary subtrees. So I might want to check out everything (as the CVS administrator), while one of the more focused developers just wants to check out /bar/baz/.

P.S. Does this list do some weird spam-blocking? I've tried 3 times now to use git-send-email to send an unrelated minor patch set (--subject-prefix for git-format-patch), and it has never shown up on the list :-(.
