More simply:  the result of `LHS ~ RHS` should be guaranteed to be zero
terminated when RHS is a StringExp.

The assert would fail anyway, because "0123" is immutable data. When you assign
"0" to s, that is different memory and cannot affect c.

Presumably this request is for:

s = "0";
s = s ~ "1";
assert(s.ptr[2] == '\0');

That would cause unnecessary writes when appending a (short) string in a loop
and each null byte is not read.
