nhmall 7d4a7a1f42 tty column placement of BL_HUNGER and BL_CAP could collide 
Change the placement of the code that makes a replica of the
current status fields for later comparison.

A loop shortcut was causing it to be skipped under some
circumstances and that was negatively impacting the placement
of status field values that were further to the right.
