Properly save 80-column drawings... possibly warn first?
        Best method (using movement codes) is as follows:
                At Start of 80-column line:
                        1) Move down one line (Using LF - force scroll if it will happen)
                        2) Move up one line (back to original position)
                        3) Save position
                At End of 80-column line:
                        1) Restore position
                        2) Move down one line using CR/LF to ensure a proper end of line
                On last line, do not do special start/end unless the last line is 80 columns.
        Second best method (for types without movement):
                At end of 80-column line, instead of \r\n, use <space><backspace>
                        - This method will not work correctly for non 80-column terminals
                        - Can result in overly long lines... breaking things which use a
                          fixed-length line buffer while reading input files (ex: ddplus doors)
