Error in G-code: bad comments lines (2 times) -> can't generate .x3g file

Hello,
I think there is 2 times a G-code error near the end of the file (after "; end_gcode..." and later after "; start_gcode...)
In general, all comments lines are aligned (lines with with 1st char ';').

After all real commands for the printer, there is additional comments

....
; duplicate_distance = 6
; end_gcode = M104 S0 ; turn off temperature\nG28 X0 ; home X axis\nM84 ; disable motors\n
; extruder_clearance_height = 20

and later
; standby_temperature_delta = -5
; start_gcode = G28 ; home all axes\nG1 Z5 F5000 ; lift nozzle\n
; temperature = 200

The problem is when the length of a line is more than 1024 chars, GPX.EXE can't manage it and it's not possible to generate .x3g for FlashForge Creator Pro printers (and others).
I must delete this line and start gpx.exe in command line.

Could you patch the next build to send a good "\n" command, please?

Sorry for my poor English!
