migrate-queries <instance-home> [<instance-home> *]
Migrate old queries in the specified instances to Roundup 0.6.0+ by
removing the leading ? from their URLs. 0.6.0+ queries do not carry a
leading ?; it is added by the 0.6.0 templating, so old queries lead
to query URLs with a double leading ?? and a consequent 404 Not Found.
