filter in get_url_in_content($content) function

[ounziw]

In WP 3.6 RC2, get_url_in_content($content) in wp-includes/formatting is

function get_url_in_content( $content ) {
	if ( empty( $content ) )
		return '';

	if ( preg_match( '/<a\s[^>]*?href=([\'"])(.+?)\1/is', $content, $matches ) )
		return esc_url_raw( $matches[2] );

	return false;
}

I propose to add filter for the return value.

	return apply_filters( 'get_url_in_content', false);

This filter will be useful in cases like this;
"when no image found, I want to return a default image (site logo or something)"

Added filter to the default return value

Fixed: just replaced the default return statement.

+1 for the filter. We should also pass $content as a second arg.

24849.1.diff includes $content as second arg.

Refreshed against trunk.

Since get_url_in_content() is only ever used by themes, themes can check the return value and return what they want. Seems like this is from 3.6RC2 and would have been way more useful if Post Formats actually happened.
