 PThe Atom format's RFC [https://tools.ietf.org/html/rfc4287#section-3
 doesn't allow for white space in date elements]:

 > Note that there MUST NOT be any white space in a Date construct or in
 > any IRI.  Some XML-emitting implementations erroneously insert white
 > space around values by default, and such implementations will emit
 > invalid Atom Documents.

 However, this was introduced in #41057 when `feed-atom-comments.php` and
 `feed-atom.php` were rewritten.

 Specifically, by:

 {{{
 -       <updated><?php
 +       <updated>
 +       <?php
 }}}

 This would cause a strict consumer to reject feeds generated by 5.1.
