 // is guaranteed to have a space between |prefix| and |suffix|.  Otherwise, the
 // result includes a space only if |prefix| has trailing whitespace or |suffix|
 // has leading whitespace.
 // A few examples:
 //  * CombineAndCollapseWhitespace("foo", "bar", false)       -> "foobar"
 //  * CombineAndCollapseWhitespace("foo", "bar", true)        -> "foo bar"
