top: allow no input with the maximum task ('n') prompt

Browse Source 
When both 'kill' and 'renice' commands were changed to
provide a default pid, the 'n' command (maximum tasks)
should have also changed to continue to accept just an
<Enter> key under the get_int function's new protocol.

This patch corrects that behavior, accepting no input.

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