Details:
Please see the end of section:
http://www.nongnu.org/avr-libc/user-manual/FAQ.html#faq_reg_usage
The docs say:
"8-bit return values are zero/sign-extended to 16 bits by the caller..."
IIRC, it is the responsibility of the called function (the callee) to clear
r25 when returning a single byte, and not the caller.
