Comment (by SergeyBiryukov):

 [attachment:miqro-28724-part2.patch] gives me a fatal error:
 {{{
 Fatal error: Can't use function return value in write context in wp-
 includes/formatting.php on line 237
 }}}
 We would need to assign `trim()` to a new variable.

 Is there a reason not to make this check the first in the loop? Can the
 regex can be modified to avoid newlines instead?
