to be safer in hostile environments where one is bullheaded enough to
give * as the command line argument.  See rants on P5P from July, 2008.

=head1 DESCRIPTION

the code is shorter than the documentation.  Please look at it.

=head2 EXPORT

None by default.

=head1 TO DO

ideally a suite of ARGV::* modules will appear, each doing their little thing,
in a way that they won't stomp on each other's toes.  This module has no
exclusion interface or anything, so an @ARGV modifier that, for instance,
preprocesses *.gz into C<"gunzip -c $_ |"> is either going to have to undo
the mods made here or be incompatible.
