Various nitpickery corrected:

    sub post_redirect {
        my ( $c, $loc ) = @_;

        my $is_rel_uri = $loc !~ m{ :// }x;

        my $is_old_proto = do {
            my $p = $c->request->protocol;
            my ( $maj, $min ) = ( $p =~ m{ \A HTTP / 0* ( \d+ ) \. ( \d+ ) \z }x );
            not $maj or $maj == 1 and $min == 0;
        };

        $c->res->redirect(
            ( $is_rel_uri   ? $c->uri_for( $loc ) : $loc ),
            ( $is_old_proto ? 302 : 303 ),
        );
    }

Main change is because HTTP versions are not floats. (Someone
tell me, when doesn’t comparing version strings properly suck?)
