QTextCursor::movePosition() with NextCursor/PreviousCursor has no effect if anchor != position

In Qt 4.4 and below, this code can be used to move a QTextCursor one place to the left or right in a QTextDocument:

cursor.movePosition(QTextCursor::NextCharacter,QTextCursor::MoveAnchor,1)

In Qt 4.5 RC 1 this has no effect if the cursor's anchor and position were different prior to calling movePosition()

This is a result of the fix for task 103115: http://labs.trolltech.com/gitweb?p=qt/snapshot/4.5;a=commitdiff;h=863c336c4f77549a7cd3eca6cbb8e787741151c5#patch80

The fix makes sense from a QTextEdit user's point of view but it breaks the semantics of NextCharacter/PreviousCharacter for programmers using QTextCursor::movePosition() and makes them different from NextWord/PreviousWord.
