okay, now i'm jumping ahead.  the sequence

	echo foo | ppt | ppt -d | ppt | ppt -d | ppt | ppt -d | ppt | ppt -d

will print foo followed by one extra newline for each invocation of
ppt -d.

since the morse -[sd] implementation led us down this twisty road, i
tried the same thing there, but found something much more
interesting...

% echo foo | morse -s | morse -d | morse -s | morse -d | morse -s | morse -d
foosss ss s 

there's some funky stuff going on there with accidentally appended s's
and spaces that seems to feed on itself quite nicely.
