Title: Discrepancy between source code and Ranges page

Public class IntProgression has function isEmpty() for example:
public fun isEmpty(): Boolean = if (increment > 0) start > end else start < end
but the sentence with the empty condition on the web page has the opposite logic. I hope I understand it clear.
