e is a binary switch both ways.  so are j and l.  U takes an argument
both ways.  g doesn't seem to be a netbsd switch.  a, o, p, and t are
handled the same way, so that's great.

my point was that you can have opt_j, opt_l, opt_U, arg_U, opt_g,
opt_a, etc, and use the options in both modes.

as to the complaints section...

	if (behavior==BSD && (opt_f || opt_g || ...))
		errx("bsd behavior invalid");

no?

of course...if you've already done it the other way...don't you have
to prescan the options for the -[BV] switch?  do you insist that it be
the first one?  what if i wanted to do "ps -uaxww"?
