Description: Ensure that the title prompt only appears once
 Windows in screen can be renamed using C-a A (title). This can be done
 repeatedly so that any number of prompts for a new window name overlay
 each other. Once the user entered a name in the topmost prompt and
 presses enter, he has to do it again for all the prompts underneath.
 This can be very confusing in case the user hit C-a A several times
 without noticing or realizing.
