I've addressed that by doing something, hopefully the right thing, if
len == 0. (We would expect len == 1).
Yeah, you're right. len==0 was the only missed case.
I didn't realize at the time that "len" doesn't include
the trailing NUL byte.

I left that because I can't see it doing any harm in this case.
It's not a big deal.
True, it causes no run-time harm, but anything unnecessary
can make the reviewer/maintainer wonder "why?".

It would have to be really really large (these are 64 bit numbers),
but yes I have fixed this too.
Updated patch is attached.
Looks fine, now.
