Description

A regexp to validate an email address according to https://html.spec.whatwg.org/#valid-e-mail-address . Note that the backslash in the name part of the regexp on that site is there to escape the forward slash, which is not needed in Go.

EDIT: This is newer than the version at https://regex101.com/library/RzBwPX, somehow a space snuck in there.
