Some users have found it necessary to add a wildcard domain as well as an abbreviated version of the same string for 'nonProxyHosts'.

For example, see how 'example.com' is listed twice:
nonProxyHosts: 'localhost | 127.0.0.1 *.nip.io | .nip.io | *.example.com | .example.com'

Please add some warning in the documentation so users can know to try this if they have problems with non-proxy hosts.
