Comment(by nacin):

 New, probably last, patch:

  - Handles multiple To: recipients via array or comma-separated string.
 Also checks if {{{$to}}} is empty first, as it could be a message with
 only CC and BCC recipients.

  - Per RFC 2822: Headers should be separated with {{{\r\n}}}, not
 {{{\n}}}. {{{wp_mail}}} now supports both so headers that work on
 {{{mail}}} work here. {{{CC: john at example.com\r\nCC:doe at example.com}}} now
 works as well.

  - Some whitespace and conventions cleanup.

 Display name handling is a bit of an edge case, so I haven't bothered with
 that here, but I'd like to see multiple recipient handling make it into
 core.
