icestats.source in /status-json.xsl is not always an array
When there is only one mount, icestats.source is an object. When there is more than one mount, icestats.source is an array. This is quite surprising, and it means that client code has to be careful to test for this case and handle it appropriately.
icestats.source should always be an array of objects describing the mounts, even if there is only one of them.
