app-shells/bash: do not update internal window title of screen and tmux The k escape sequence changes the internal window title of screen and tmux, which is an alias given to the window by the user. The alias can be used to reference the window in internal commands, e.g. by using "select <alias>" in screen or "select-window -t <alias>" in tmux to switch to a window by name, and should not be updated by commands running inside of screen and tmux.
