On a note half way between here and there, the above is a good example
of what one could do with a commented disassembly. Is not perfect but
the avr tools can disassemble and comment an object file as a target in
the Makefile. Often all that is needed is a glance at that file's
contents to realize the code is not going to do what one expected.

Also good for tuning one's C coding style for maximum avr-gcc
