richedit: Removed incorrect FIXME comment.

The fixme comment is suggesting wrapping a paragraph within a function
that is for moving the selection cursor up or down a line when the up
or down keys are pressed.  The contents fo paragraph aren't being
changed, so there is no need to wrap the paragraph.
