Typo in top 2.5

[Rick Adams]

If you actually look at the code you will see that on most
real systems it makes absolutely no difference!

The test is to see if the maximum pid hsa increased since the
last window update.

Given that the window updates are on the over of several seconds,
if your system hasn't created a new process in that time
period, then its idle anyway, so who cares?

yes, its clearly a bug, but its not a big deal.
