clean up terminal in a specific situation

The problem: if ever I hit ctrl-e to go to the big picture view and then
hit Esc to go back to running the app, my terminal was messed up after
exiting the app.

Why did I even have this gunk? Perhaps it dates from the time when kilo
was emitting raw escape sequences rather than using ncurses.
