Allow the repl to show source code and complete tracebacks

[pablogsal]

Currently the REPL doesn't show traceback source or augmented information for the source that is typed in the repl itself:

>>> def f(x):
...    1/x
...
>>> f(0)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 2, in f
ZeroDivisionError: division by zero

To improve user experience, we want the REPL to be able to treat source lines thar were typed directly as any other kind and show proper tracebacks:

>>> def f(x):
...    1/x
...
>>> f(0)
Traceback (most recent call last):
  REPL, line 1, in <module>
    f(0)
  REPL, line 2, in f
    1/x
    ~^~
ZeroDivisionError: division by zero
