WordPress.tv: Filter intended to prevent orphaned words creates them

[SergeyBiryukov]

On WordPress.tv, there's a code that adds   before the last word in video titles.

I could not find it in the open sourced theme, but I guess it's similar to rosetta_orphan_control() in Rosetta:

/**
 * Makes final space a non-breaking one, to prevent orphaned word.
 *
 * @param string $string
 * @return string
 */
function rosetta_orphan_control( $string ) {
	return substr_replace( $string, ' ', strrpos( $string, ' ' ), 1 );
}
add_filter( 'no_orphans', 'rosetta_orphan_control' );

The problem is that it doesn't work well for languages with longer words, see the screenshot.

As seen on ​http://wordpress.tv/event/wordcamp-moscow-2016/, this title does not wrap correctly with  :

Варвара Лялягина: Как стать идеальным заказчиком

The function should probably only replace spaces preceded by shorter words (1 to 3 letters or so).

In 6380:

WordPress.tv: Roll our own widont.

On all index/archive screens, titles don't have a lot of room. The built-in minimum of 10 chars is not too helpful for this theme—let's see how 8 will fare.

Fixes #2106.
