Comment (by solarissmoke):

 Was going to open a new ticket but I think it can be addressed here:

 `do_enclose()` does not check that the response to `wp_get_http_headers()`
 was good (i.e., HTTP 200) before trying to process it. That means that if
 you happen to have a link that is either broken or redirected (301), it
 doesn't realise this and still tries to parse the result, resulting in PHP
 notices (e.g., missing content-length header).

 Two things:

 (1) We should at least be checking for a 200 response

 (2) Maybe we could be clever and follow 301 redirects. Seeing as there are
 so many shortlinks floating about everywhere, I think this would greatly
 increase the number of hits for `do_enclose()`
