Currently if you resize an xterm that top(1) is running in to too few lines
for any processes to be shown and then type 'n' to show X process lines, top
will display a message saying:
This terminal can only display -Y processes.
Obviously a negative number is not quite correct. This diff makes top display:
This terminal can only display 0 processes.
Perhaps the grammar is not great...but...
ok?
