using -p index, a target pane is now addressed with the normal -t window form but suffixed with a period and a pane index, for example :0.2 or mysess:mywin.1. An unadorned number such as -t 1 is tried as a pane index in the current window, if that fails the same rules are followed as for a target window and the current pane in that window used. As a side-effect this now means that swap-pane can swap panes between different windows. Note that this changes the syntax of the break-pane, clear-history, kill-pane, resize-pane, select-pane and swap-pane commands.
