Re: more/less/p

At Fortune Systems Dave Yost added page mode to the tty driver
when his serial io optimizations made scrolling at 9600
blazing fast.  He also added an ioctl for page size.  By
setting it to something smaller than the tty number of rows
you can see some context as well.  This worked pretty well.
