IMO, we should first decide whether this new behavior should be the
default, and only after that whether it should be controlled by a
command-line switch.  E.g., if we believe that most users will want
the backtrace, i.e. the default behavior will be to produce a
backtrace, then a command-line switch is hardly necessary or
justified.
