 I wrote a unit test with a few assertions to confirm that this is still
 happening, and looks like it is.

 I've created a PR that includes both [attachment:"19847.2.diff"] and the
 unit test, and looks like it does the trick. The `-1` is not actually
 required anyway since the `trim()` call in the following lines will also
 remove the space (if present).

 Looking at how the headers are passed to PHPMailer, each one is expanded
 using `explode()` before performing some basic trimming and adjusting to
 be in the proper format before getting passed. For the from name and from
 email, `setFrom()` within PHPMailer expects them to be passed as separate
 parameters in order to perform some of its own validation.

 With this in mind, we could add a `__doing_it_wrong()`, but I'm not sure
 it's really necessary since PHPMailer will reconstruct the header
 correctly with the space later on.
