Bug description:

Consider this:

for a in b:
    pass
elso:
    pass

>>> for a in b:
...     pass
... elso:
...     pass
...
  File "<python-input-0>", line 3
    elso:
    ^^^^
SyntaxError: invalid syntax. Did you mean 'else'?

but

  File "/Users/pgalindo3/github/python/main/lol.py", line 3
    elso:
         ^
