Comment:

 I think generating an E_WARNING based on external (pingback) output is not
 great. We should probably avoid that. At this point, it's a bit late to
 patch wp_remote_retrieve_header() (I agree with concatenating into a
 string) but maybe we can just do a cast/implode/pluck here.

 Alas, in a few other places we use wp_remote_retrieve_header(), we also
 don't expect the array. So maybe punt and fix later. dd32?
