#1219 Wrong code formatting

[ntp]

Type and then format code:

def test():
x = {
'a': 1, # two spaces before comment (PEP8)
'b': 2
}

return -1

Actual result:

Only one space before comment and '- 1'.

def test():
x = {
'a': 1, # two spaces before comment (PEP8)
'b': 2
}

return - 1

Expected result:
No changes should be made
