SPACES_BEFORE_COMMENT column mode violates PEP8 policy of two spaces before comment

[reagle]

Now that #667 is resolved, I have a concern about the behavior: specifying multiple values so as to use column alignment results in inline comments preceded by a single space. Shouldn't there always be two spaces as a minimum regardless of column alignment?

For example, this PEP8 compliant code:

else:
    class args:
        cgi = True                # called from cgi
        chase = True              # Follow freeplane links to other local maps
        long_url = False          # Use short 'oldid' URLs for mediawikis
        urls_online_only = False  # Emit urls for @online only
        pretty = False            # Print as HTML with citation at end
        query = None              # Query the bibliographies
        query_c = None            # Query re.compiled

loses a space

else:

    class args:
        cgi = True               # called from cgi
        chase = True             # Follow freeplane links to other local maps
        long_url = False         # Use short 'oldid' URLs for mediawikis
        urls_online_only = False # Emit urls for @online only
        pretty = False           # Print as HTML with citation at end
        query = None             # Query the bibliographies
        query_c = None           # Query re.compiled
