Spelling.
Abort on allocation failure (with errx()).

fixed variable so all manually-specified devices are shown rather then
cutting the display off at 3, fixed formatting for msps when msps is
larger then 100 (it was blowing the columner display output before),
added -K option to make blk count (-oIK) force a 1K block size (to conform
more closely to systat, vmstat definition of blocksize).
