top: improve the response to ^Z if awaiting line input

Browse Source 
Now that line input offers users full editing freedom,
if top were to be suspended after issuing a prompt for
input, upon resumption an extra keystroke is necessary
to satisfy the outstanding read & refresh the display.

With this patch that extra keystroke is not necessary.

(everything is perfectly justified plus right margins)
(are completely filled, but of course it must be luck)
