Enter key after line rollover returns to original position + 1 line

Enter key after line rollover returns to original position + 1 line, instead of intended behaviour of moving to the next line as visually indicated

While writing the text below in the OS, while writing the second line, I realised that a word I was writing was going to be written over two lines, and decided to move to the next line using the enter key to give the next word space, but when hitting enter, instead of moving me to the next line, it sat me back at the start of the second line, overwriting the text "to video memory..." etc.

This could potentially be fixed by checking when the cursor is at the right edge of the screen, and calling the setCursor function when rolling over to the next row.
