Fix behaviour when inserting a line due to wrap from a line with a hard CR

Previously, the hard CR was retained, and the wrapped test was added to the
beginning of the next line.  Now the hard CR is cleared from the original
line and set on the newly inserted line.  We also need to redraw lines
after the inserted line now.
