Josh Steadmon 87c2d9d310 filter-options: expand scaled numbers
When communicating with a remote server or a subprocess, use
expanded numbers rather than numbers with scaling suffix in the
object filter spec (e.g.  "limit:blob=1k" becomes
"limit:blob=1024").

Update the protocol docs to note that clients should always perform this
expansion, to allow for more compatibility between server
implementations.
