PSR2 MethodArgumentSpacerFixer clean additional spaces

PSR2 MethodArgumentSpacerFixer clean additional spaces after a comma.
With this code one and only one space can be after a comma in a method call.

> 4.4. Method Arguments
> In the argument list, there MUST NOT be a space before each comma, and there MUST be one space after each comma.

Thanks
If `\n` may or may not be preceded by `\r` then you can simply check only `\n`, can't you ?
