I know you didn't write that comment but I thought I'd clarify what
it is referring to, having written some or all of that part of GCC.
There's nothing unintentional at all; in fact it is natural - if
you're left-shifting out wchar_t bits worth of bits, and adding in
the new value of wchar_t bits, you get just the new value.  In
generic code this wouldn't be a special case.

char is what's special here - they have type int but get shifted
in a char width at a time.
