Comment (by bpetty):

 Latest patch takes all discussion up to this point into consideration,
 specifically, it *only* updates `class-phpmailer.php` and `class-smtp.php`
 in place while post-patching files to remove the autoloader and manually
 include `class-smtp.php` as necessary.

 It passes [https://travis-ci.org/tierra/wordpress/builds/19137930 unit
 tests]. I've also manually tested this by hand with Bluehost hosting with
 the given headers delivered ('To' and delivery path headers stripped):
