 Supply better data for top's CPU state display. Currently top has
 to subtract old numbers from new numbers and divide that result by
 the number of processors. The kernel won't even supply the number
 of processors in a portable way.

 Better unmangling of '?' as a tty. The shell destroys '?' when there
 is a filename that matches. If the argument seems like garbage,
 check for a file that might have screwed up the '?'.
