Synopsis example does not work in latest version

[akauste]

enable "Plack::Middleware::XForwardedFor",
trust => [qw(127.0.0.1/8)];

Works as intented in version 0.103060, but not with 0.172050. It is not tested. Tests use value 127.0.0.1 which works, but there are probably many people using the synopsis code which now starts failing when the module is updated.

Looking further it looks like Net::IP does not like bits set after the mask. 127.0.0.0/8 is ok, but 127.0.0.1/8 is not.
