Pylint: Unnecessary "else" after "return" false positive

[sambarluc]

This seems to be a regression in 2.0.

Steps to reproduce

def function(val):
    if val == 1:
        return 1
    elif val == 2:
        return 2
    return 0

Current behavior

This currently raises:

pylint_bug2.py:2:4: R1705: Unnecessary "else" after "return" (no-else-return)

Obviously, I am ignoring the complaints on the docstrings.

Expected behavior

Well, the code avoids precisely the issue raised by pylint, there is no else!

[sambarluc]

Ok, and that's a feature, apparently.

Yes, that's a feature.
