Phut!  I should have tried this before advocating the benefits of using
\once.
It doesn't work.
It seems breaks must be On for at least 2 time steps to be effective.
So using
\autoLineBreaksOn
b' b'
\autoLineBreaksOff
in the middle of a long sequence with Off, permits a break after the two
b's,
but
\autoLineBreaksOn
b'
\autoLineBreaksOff
or using \once does not permit the break, or at least the opportunity is
not taken
and the line runs off the right margin.

So we need a \twice command ;)
