Or maybe not.  It's a simple enough change, but it breaks all our
regression tests, which use -a and are not expecting blank lines to
get echoed.  So I think I was right the first time: the existing behavior
is probably embedded in enough places that changing it would not be worth
the pain.  Sorry.

This still needs fixed though ...
