2003-06-13 Nathan C. Myers <ncm-nospam@cantrip.org>
Avoid multi-processor bus contention on increment/decrement-and-

addresses first, and never touching the reference count of the empty-
string object.

a base class _Rep_base.
(_Rep::_M_dispose, _Rep::_M_refcopy): Check for the empty string.

since no longer must increment its refcount.

return immediately. The former might be unnecessary. The latter
prevents begin() and end() from cloning it unnecessarily.

This is necessary here because _M_mutate is sometimes called with
all-zero arguments; in all other uses of _M_is_shared, the test comes
out right anyhow.
