Text Justification should not apply to last line or before line breaks

[kribensa]

When using a TextFormatAlignment with Horizontal = XParagraphAlignment.Justify on a large block of text, the main block of text is correctly justified, but the last line, which often contains much less text than would fit on a line is "over" justified and very spread out A similar issue occurs on the line before a line break

eg

I would have expected it to Left Justify the last line, resulting in this nicer looking text
