The hack I was fooling with yesterday would have had that effect,
although it was a consequence of the fact that I was too lazy
to parse slash-star comments ;-).  But basically what I was
trying to do was to force a line that was only whitespace
(possibly plus dash-dash comment) to be treated as a separate
history entry, while not suppressing dash-dash comments
altogether as the current code does.
