You've probably seen that tools/command-lines.in is where we now define
the options accepted by each command.  But, many commands still contain
redundant option checking that could be removed.  So, nearly all of the
option checks in pvdisplay can be removed, not just -a (and many of the
option combination rules can also be defined in command-lines.h.)  If
you'd like to send a larger patch for pvdisplay then we could apply
that instead.
Thanks, Dave
