>Description:
	'iostat -x' is very nice when monitoring many disks, but the output
        would be a lot more 'pleasing' to the eye if it would print the
        header at each update instead of just when deemed necessary. Currently
        there is a tendency to constantly have to search for the header
        when monitoring continously. This becomes distracting with many disks
        because the location of the header on screen becomes quite erradic.
>How-To-Repeat:

>Fix:

I propose the following patch to make iostat print headers for each update when
running in extended mode.
