Invalid handling of arrayref results with redirects

[berekuk]

If rules code returns arrayref with 3xx status, its location is ignored, usually resulting in infinite redirect.
Example:

use strict;
use warnings;

use Plack::Builder;

builder {
    enable 'Rewrite', rules => sub {
        return [ 302, [ Location => '/foo'], [] ] if /bar/;
    };
    sub {
        my $env = shift;
        return [200, [], [ "Path: $env->{PATH_INFO}" ] ];
    };
};

This app produces an infinite redirect if asked for /bar url.

PS: The reason I'm using it this way instead of substituting $_ and returning 302 is that I call external $app on different rules, and they handle some rewriting themselves.

Thanks for the report. Fixed in 9e71965. Release 1.005 is winding its way to the CPAN, you should have it soon.
