Indentation level of else:-type lines is not reduced #771

Environment data

VS Code version:

1.20.0
c63189deaa8e620f650cc28792b8f5f3363f2c5b
x64

Python Extension version: 2018.1.0
Python Version: 3.6.3
OS and version: Ubuntu 2017.10 AMD64

Actual behavior

After typing enter at the end of a line such as else:, elif cond:, except:, finally:, the indentation level of that line is unchanged and the next line is auto-indented to the wrong level as well:

if cond:
    do_stuff()
    else:|

after typing enter, becomes

if cond:
    do_stuff()
    else:
        |

Expected behavior

if cond:
    do_stuff()
    else:|

after typing enter (or : on atom if I remember correctly), should become

if cond:
    do_stuff()
else:
    |

Steps to reproduce:

• Use a construct as if-elif-else, try-except-else-finally.

Is this normal? I expect that this is a problem with my setup and not this extension given the simplicity of the issue, but my install is as standard as can be...
