Description:
	Trying to use hardware tabs at the console of a 780 doesn't
	work properly.  Apparently the LSI-11 software expands
	tabs and characters with the parity bit set confuse its
	calculations.
Repeat-By:
	Log on at the console of a 780 and type 'stty tabs'.  Do an
	'ls /' and note the uneven columns.
Fix:
	Don't set the parity of characters going to the console.
