[issue4857] syntax: no unpacking in augassign

[jura]

New submission from jura <jura05 at narod.ru>:

the following code produces syntax error:
>>> (x, y) += 1
While this is documented in
http://docs.python.org/3.0/reference/simple_stmts.html#augmented-assignment-statements
("An augmented assignment evaluates the target (which, unlike normal
аssignment statements, cannot be an unpacking)..."),
the syntax specification doesn't reflect this:
http://docs.python.org/3.0/reference/simple_stmts.html#grammar-token-augmented_assignment_stmt
http://docs.python.org/3.0/reference/grammar.html
