I got no feedback at all on the humanize_number(3) function that I
submitted before (PR#15508), which is a bit strange considering how
many people that suggested it...
I admit that I did submit it in the wrong category (bin instead of lib)
and it's not a complete ready-to-go patch, but I don't know where to
put the flag defines and the function prototype, maybe creating a
/usr/include/humanize.h would be the best?
