Initial patch
Spent quite a long time but was not able to create a layout test.
1. In Mail the end text marker of left line range has upstream affinity but I tried left/right and regular line text marker range call in layout test it gave downstream affinity all the time.
2. Although I had the fix to adjust CharacterOffset to match Range's end offset, TextIterator will always include an extra space at the line wrap. So there's no easy way to test this fix in a layout test by using lengthForTextMarkerRange of stringForTextMarkerRange, they all use TextIterator under the hood.</pre>
