Implement positive values for <depth> in the tree:<depth> filter. The exact semantics are described in Documentation/rev-list-options.txt. The long-term goal at the end of this is to allow a partial clone to eagerly fetch an entire directory of files by fetching a tree and specifying <depth>=1. This, for instance, would make a build operation fast and convenient. It is fast because the partial clone does not need to fetch each file individually, and convenient because the user does not need to supply a sparse-checkout specification. Another way of considering this feature is as a way to reduce round-trips, since the client can get any number of levels of directories in a single request, rather than wait for each level of tree objects to come back, whose entries are used to construct a new request.
