Fix for some sample bugs

a + b ? c : d does not do what I think it does.  That bug mostly masked
a thorough logic error in building the table of counts of possible sequences;
there was too much cumulativeness.

There apparently remain problems

\foreach \y/\col in {0/29,0.2/49,0.4/57,0.6/17,0.8/6} {
  \fill[black!\col!white] ($(-0.1,0)+(0,\y)$) rectangle ($(0.1,0.2)+(0,\y)$);
}
