net/mail: AddressList fails to parse addresses with a dot

[eaigner]

Header.AddressList(key) fails to parse the following address

    Asem H. <noreply@n.testflightapp.com>

I tested several addresses with whitespace, quotes, etc., and that's the only one with a
dot, so I assume that's the problem.

Comment 1:

That address doesn't conform to RFC 5322. The display-name needs to be quoted.
  "Asem H." <noreply@n.testflightapp.com>

Labels changed: removed go1.1maybe.

Status changed to WorkingAsIntended.

Comment 2:

I know, but mail headers floating around are malformed more often than not. Wouldn't it
be better to make the parser more lenient?

Comment 3:

I see no problem with making the mail parser accept this address, but I'd
like to postpone it until after Go 1.1. Thanks.
