Chao's decision to include the row and column headers makes more sense to
me.  The promise of this feature is that the visual output of booleans as
t/f should go away if the user chooses to make use of these
local variables.  While we may not be able get them all (e.g.,
composites and arrays) doing so here is trivial to accomplish.
