Description

IronPython repl gives SyntaxError for multi-line statement within a block. It handles it OK for top-level statements, but not for statements within blocks which are already indented according to python rules. In the below steps, this is within a function definition.

Steps to Reproduce

Attempt to enter the following code in the repl:

def f1(a,b):
  return a+b

def f2(a,b,c):
  return f1(
    f1(a,b),
    c)

f2(1,2,3)

Expected behavior: [What you expected to happen] The CPython repl accepts the code:

Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 27 2018, 04:59:51) [MSC v.1914 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> def f1(a,b):
...   return a+b
...
>>> def f2(a,b,c):
...   return f1(
...     f1(a,b),
...     c)
...
>>> f2(1,2,3)
6
>>>

Actual behavior: [What actually happened] The IronPython 2.7.8 repl doesn't accept the code:

IronPython 2.7.8 (2.7.8.0) on .NET 4.0.30319.42000 (64-bit)
Type "help", "copyright", "credits" or "license" for more information.
>>> def f1(a,b):
...   return a+b
...
>>> def f2(a,b,c):
...   return f1(
  File "<stdin>", line 3

    ^
SyntaxError: unexpected token '<newline>'

It also works with the CPython 2.7 repl:

Python 2.7.15 (v2.7.15:ca079a3ea3, Apr 30 2018, 16:30:26) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> def f1(a,b):
...   return a+b
...
>>> def f2(a,b,c):
...   return f1(
...     f1(a,b),
...     c)
...
>>> f2(1,2,3)
6
>>>
