Did you look at how the byte compiler determines the line number it
will include in the warning/error message? If you didn't, you should,
because after you do, you will never again wonder why an incorrect
line number is reported. In fact, now that I did look there, I'm
surprised it reports a correct line number at all, let alone as often
as it does. It's sheer luck.
