  Log:
  Reduce the field width by 1 for many numeric fields so that most fields
  cannot run into other fields or field descriptors.  If the value is
  too large to fit in the field width, then the output format is adjusted
  so that the value (usually) fits, but with fields running together
  externally this adjustment usually didn't help.  Mostly it doesn't
  matter to lose 1 digit of precision, but switching the output format
  is bad if it happens often or gives bogus units.  The loss of width
  is most serious for fields near "Csw" (which are also the ones which
  must often ran together) since these have a high variance and large
  values relative to the possible field widths so the switch occurs more
  often now, and for the memory size fields where the switch gives the
  bogus units kKB or MKB.
  
  Now only the fields for r, p, d, s and w can run into each other.
  These fields have width 3, and 3 cannot be reduced to 2 without losing
  all precision when the value is between 100 and 999.
  
  Trim "pdwake" to "pdwak" at think time now that it doesn't get clobbered
  at runtime.  The manpage doesn't need to be changed for this because
  it documents the clobbered descriptor, unlike for 4 other too-long
  descriptors which only get clobbered if there are lots of interrupt
  sources.
  
  Trim "% busy" to "%busy" since most other descriptors for percentages
  are spelled without the space and this change makes changing the widths
  of the %busy fields unnecessary.
