bpo-45463: Clarify that global statements allows multiple names (GH-28851) 

The global statement allows specifying a list of identifiers

occur anywhere within a code block. The local variables of a code block can be
determined by scanning the entire text of the block for name binding operations.
If the :keyword:`global` statement occurs within a block, all uses of the name

If the :keyword:`global` statement occurs within a block, all uses of the names
specified in the statement refer to the bindings of those names in the top-level
namespace. Names are resolved in the top-level namespace by searching the
global namespace, i.e. the namespace of the module containing the code block,
and the builtins namespace, the namespace of the module :mod:`builtins`. The
global namespace is searched first. If the name is not found there, the

The :keyword:`global` statement has the same scope as a name binding operation
