Also, I normalized them to all be sentences for consistency, and I moved the reentrancy check from `m.mount` to `m.render` to be a little more helpful. The router change during mounting is inconsequential and only to avoid the new modified error, and the change to the update loop is to send the original error if an error occurred while initializing the default route. (This is all around more useful anyways.) And while I was at it, I fixed an obscure bug with sync redraws.
