extended header sending error with \n

[richardturnnidge]

I found an odd error sending if certain \n order is used in a printf() function.

This will upload fine:

      printf("nunchuck_joyD      " BYTE_TO_BINARY_PATTERN, BYTE_TO_BINARY(nunchuck_joyD) ); 
      printf("\n"); 
      printf("\nnunchuck_angleX    %d   \n", nunchuck_angleX); 

This gives error:

      printf("nunchuck_joyD      " BYTE_TO_BINARY_PATTERN, BYTE_TO_BINARY(nunchuck_joyD) ); 
      //printf("\n"); 
      printf("\nnunchuck_angleX    %d   \n", nunchuck_angleX);

Extended header sending error, aborting
make: *** [upload] Error 1

The only difference is the insertion of \n

It appears to be an issue if the next char is another (single) n

I've tried to reproduce this with (and other variants)
#include <stdio.h>

int main(int argc, char ** argv) {
printf("Hello world");
printf("\n");
printf("\nnunchuck %d \n", argc);
return 0;
}

However, this uploads just fine. Not sure what's happening with the BYTE_TO_BINARY_PATTERN, I don't have access to that.
