A carriage return (enter key) will increase the _distanceEnd by up to
viewport-width many columns, since it increases the Y distance between
the start and end by 1 (it's a newline after all).
This will make _flushBuffer() think that the new _buffer is way longer
than the old one and so _erase() ends up not erasing the tail end of
the prompt, even if the new prompt is actually shorter.
This commit fixes the issue by separating the newline printing
out from the regular text printing loops.
