Yes, I know that ;) And I also know that implementing the exact behaviour you
want would be trivial and would bring consistency between signed and unsigned
char platforms. Probably we want to implement it anyway in v3, but that doesn't
mean by itself that it's obviously the only meaningful interpretation of the
standard if so many other implementations differ, as pointed out by Martin. 

Thus let's be clear about that with Martin and probably at the same time also
take actions to open a DR for C++0x.
