From: Oguzhan Unlu <cengoguzhanunlu@xxxxxxxxx>
My solution to make lines containing buffer += a_number; clearer to anyone is following; I defined a new int, magic_num, then assigned lengths of used strings to magic_num and then changed assignment lines through using magic_num so that where the number which is added to buffer is known although I eliminated 3rd parameter of memcmp() when using starts_with().

I didn't use skip_prefix() in this microproject and I plan to apply for GSOC 2014. I expect your feedbacks!
