I am coming around... I think we may have been too hasty in making
this behavior the default. While I see how the current default can be
useful, that usage feels like it would be far less common than the
usage/expectation that provokes surprising (and likely to provoke
malfunction) behavior.

What do you think, Paul? Switch the default and add an option for the
current-default `--max-count=N`-trumps-`--context=N` behavior?
