WrapAtWordBoundaryOrAnywhere does not work as documented.

The name and documentation of QTextOption::WrapAtWordBoundaryOrAnywhere suggest that it behaves like WordWrap whenever it can, and like WrapAnywhere as a fallback when it can't.

Instead, when the QTextEdit is in FixedColumnWidth mode, it seems to behave like WrapAnywhere all the time. I have not managed to make it wrap at a word's boundary in any case where FixedColumnWidth was used.

If WrapAtWordBoundaryOrAnywhere is really intended simply as an alias for WrapAnywhere, the documentation should probably reflect it.
