and not have to wait for an update when they change pane, we allow commands to run more than once a second if the expanded form changes. Unfortunately this can mean them being run far too often (pretty much continually) when multiple clients exist, because some formats (including #D) will always differ between clients. To avoid this, give each client its own tree of jobs which means that the same command will be different instances for each client - similar to how we have the tag to separate commands for different panes. GitHub issue 889; test case reported by Paul Johnson.
