Ignore URLs with 'iPhone 6+' in the string
Ignore URLs with 'iPhone 6+' in the string

The library html-proofer uses to verify these urls is incorrectly converting
the string '%2b', which is a url-encoded plus sign, to a real '+'. These URLs
work with a sane URL parser, so prevent HTML proofer from proofing these URLs.
