Don't print two newline at end of line.

After printing a character, the code would previously automatically start
a new line when the right side of the screen was reached.
Thus, printing a newline at the end of a line resulted in two newlines
being printed.

The new code prints starts a new line only *before* printing non-CRLF
characters.
