That MAX_COLS change in it makes `top -b' produce too much extra
whitespace that's not trimmed and spans several lines, e.g.

  $ stty -a | sed 1q
  speed 38400 baud; 57 rows; 79 columns;
  $ top -b
  last pid: 54799;  load averages:  1.90,  2.16,  2.16  up 0+04:28:34    10:18:15

FYI, using inverse color for header line can also be achieved on
top-3.8b1 without touching source at all

  $ export TOPCOLORS='header=,#7'

edwin@ planned to update top(1) but stalled, not sure why.

And I for one still use his branch with below diff.
