#1442 Code formatter conflicts with PEP8 E261

[Anonymous]

When a line ending with a comma (for example, when each entry in a dict or a list is on its own line) is followed by an inline comment and the code formatter is enabled, the line is always changed to put a single (or none, depending on the configuration) whitespace between the comma and the comment. This contradicts the PEP8 rule E261 "at least two spaces before inline comment" and creates a warning if PEP8 is enabled.

When there's an inline comment, the code formatter should put two whitespaces after the comma.
