cbexport could easily filter on key prefix (or by regex)

I answered a forum post (link) and wrote a simple archiving Eventing function

function OnUpdate(doc, meta) {

    if (! meta.id.startsWith("doc-wigitcompany-")) return;

    dst_bkt[meta.id] = doc;

}

Then I used cbexport to extract my matched documents from a dedicated archive bucket.

/opt/couchbase/bin/cbexport json -c couchbase://127.0.0.1 -u $CB_USERNAME -p $CB_PASSWORD -b archive -f lines -o /tmp/tmp.out.json

It became apparent that a simple enhancement to the cbexport tool to allow it to filter by key prefix (or by regex) would allow me to skip the Eventing step I proposed in the forum post altogether.   

Perhaps options like -m, --match_key_prefix and -r --match_regex_key could be added.  I am assuming that cbexport is a fast DCP consumer here.
