* Use tmux to list keybindings
* Annotate tmux keybindings
* List unannotated bindings too and let the isolated server exit on its own
list-keys -aN falls back to the raw command when a binding has no note,
so user-added bindings in an existing tmux.conf still show up. Dropping
exit-empty off means the throwaway server exits when the client
disconnects instead of relying solely on the trap.
