the state (client, session, winlink, pane) for it it before entering the command. Each command provides some flags that tell the prepare step what it is expecting. This is a requirement for having hooks on commands (for example, if you hook "select-window -t1:2", the hook command should to operate on window 1:2 not whatever it thinks is the current window), and should allow some other target improvements. The old cmd_find_* functions remain for the moment but that layer will be dropped later. Joint work with Thomas Adam.
