richedit: Made sure the caret position is stored when moving up/down.

The caret's x position is stored in ME_TextEditor.nUDArrowX so that when
the caret is moved up or down, it will stay along the same horizontal
position, or at the end of a line.  Unfortunately, the value stored in
nUDArrowX was being unconditionally discarded in ME_ArrowKey, preventing
it from serving its purpose.
