Windows test issues

[TBSliver]

Have fixed a minor bug in t/Plack-Handler/output_encoding.t in #648 due to spaces in filenames, however I get another bug during the Standalone tests:

Not enitrely sure why this is, but its during the return glob test:

Plack/lib/Plack/Test/Suite.pm

Lines 139 to 159 in 7435902

	[
	'return glob',
	sub {
	my $cb = shift;
	my $res = $cb->(GET "http://127.0.0.1/");
	is $res->code, 200;
	is $res->message, 'OK';
	is $res->header('content_type'), 'text/plain';
	like $res->content, qr/^package /;
	like $res->content, qr/END_MARK_FOR_TESTING$/;
	},
	sub {
	my $env = shift;
	open my $fh, '<', __FILE__ or die $!;
	return [
	200,
	[ 'Content-Type' => 'text/plain', ],
	$fh,
	];
	},
	],

Note this is using the fixed version of TCP::Test from tokuhirom/Test-TCP#96 as well.
