Comment:

 It seems like a bug to me, since Core is using `AddCustomHeader()` instead
 the appropriate method, and that causes an undesirable result. I think
 plugin authors have a reasonable expectation that they can add a `Reply-
 To` header without any extra fuss.

 I don't see any drawback to making `wp_mail()` use `AddReplyTo()`, and if
 we do that then it would "just work" for everybody. If we don't, then any
 plugin dev who wants to set a `Reply-To` will potentially get bit by this;
 and if they do, then they'll have to spend a lot of time figuring out what
 happened and how to work around it.

 I attached a first attempt at a patch in case others think it'd be a
 positive change.
