UILineBreakModeWordWrap whitespace problem

i have made a small correction in the logic on line no 183, so that when the line breaking mode is UILineBreakModeWordWrap, the leading and trailing whitespaces are not truncated.

Now the words are correctly assembled back from the characters when the text width exceeds container width.

request to merge this change with your code.
