IMHO it's no bug. The code performs what it's supposed to do. But you may
classify this as a Request For Enhancement. Maybe it even already is.

Btw. I see DJNZ twice ;-)

But you may recompile this with -fverbose-asm to also view the iCodes and
the used peephole rules. These can point to places where optimizations can
be extended.
