Filter for http:// to remove p tags for WYSIWYG

This issue is in reference to this issue → , but a little different so i wanted to make another issue to track it.

In the other issue the problem was coming from the [embed] tag, however what I'm up against is the filter picking up the URL without the embed tag. The issue is that WYSIWYG always place a

tag on any new line. Since the function below is only looking for a patttern that matches http it rejects the string as a pattern match.

While its not idea for the module at large, is there anyway I can check for the pattern along with

to ensure that it always gets read and converted?

function oembed_filter_oembed_prepare($text, $filter, $format, $langcode, $cache, $cache_id) {
  if ($filter->settings['autoembed']) {
    $pattern = '|^\s*(https?://[^\s"]+)\s*$|im';
    $text = preg_replace_callback($pattern, 'oembed_preg_auto_replace', $text);
  }
  return $text;
}
