[issue4907] ast.literal_eval does not properly handled complex numbers

[Armin Ronacher]

New submission from Armin Ronacher <armin.ronacher at active-4.com>:

ast.literal_eval does not properly handle complex numbers:

>>> ast.literal_eval("1j")
1j
>>> ast.literal_eval("2+1j")
Traceback (most recent call last):
  ...
ValueError: malformed string
>>> ast.literal_eval("(2+1j)")
Traceback (most recent call last):
  ...
ValueError: malformed string

Expected result:

>>> ast.literal_eval("1j")
1j
>>> ast.literal_eval("2+1j")
(2+1j)
>>> ast.literal_eval("(2+1j)")
(2+1j)

I attached a patch that fixes this problem.
