By default, tmux will show the title of the focused pane in the status bar. After using
rename-window to set a title manually, how do you restore the default behavior?
First idea was to set a blank title, which didn't work. According to the soruce code, it sets the window option "automatic-rename" to 0, but doing things like
setw -g automatic-rename on doesn't seem to have any effect (aside from confirming that the option was set).
