pane.Pane.exit_mode

A pane that is in no mode is left alone rather than refused, so this can be called to reach a known state without asking first.

This dispatches copy-mode -q rather than the cancel key, because the key reaches a pane through the copy-mode key table and clock mode and tree mode have none: sending it there is answered "not in a mode" while the pane stays in one. -q is the only exit that covers every mode, including the ones Self::clock_mode and choose-tree create.

Errors
