Clients MUST send all the obj-ids it wants from the reference
result are defined as shallow and marked as such in the server. This
information is sent back to the client in the next step.
+The client can optionally request that pack-objects omit various
+objects from the packfile using one of several filtering techniques.
+These are intended for use with partial clone and partial fetch
+operations. An object that does not meet a filter-spec value is
+omitted unless explicitly requested in a 'want' line. See `rev-list`
+for possible filter-spec values.
+
Once all the 'want's and 'shallow's (and optional 'deepen') are
transferred, clients MUST send a flush-pkt, to tell the server side
that it is done sending the list.
