creatFragmentFromText, in markup.cpp, was splitting the string “\n” into two strings, one empty, and thus creating two elements to represent the line break, one empty <div> and one <br>. This resulted in the emission of an additional “\n” corresponding to the empty <div> during text extraction (TextIterator.cpp line 1152). The change in CharacterIterator::range is to properly handle the case where a text run consists of a <br> element. Before It was treated as CharacterData and not as a node range.
