gh-139871: Add _PyByteArray_empty_string to the stable ABI by vstinner · Pull Request #140770 · python/cpython

#140128 tried to remove _PyByteArray_empty_string by mistake which would break the stable ABI. Let's put it in the stable ABI to detect if it's removed by mistake.

It's not part of the stable ABI; it's certainly not in the Windows stable ABI DLL.
Let's not add it.

Oh, it's declared in Include/cpython/bytearrayobject.h, not in Include/bytearrayobject.h, you're right.
