Feature request: .editorconfig supports commas at end of certain members

[heaths]

To reduce the complexity of diffs (and merges with said diffs), we prefer developers use commas after the last member of enums, and object and collection initializers like so:

enum ExampleEnum
{
  Foo,
  Bar,
}

new ExampleClass
{
  Foo = 1,
  Bar = "str",
}

new[]
{
  "foo",
  "bar",
}

It would be great if .editorconfig supported commas in these cases, as mere suggestions, required, or forbidden as with other rules.

Nice suggestion! Also tagging @kuhlenh and adding it to our backlog.

📝 An implementation of this style rule is currently available in StyleCop Analyzers. It proved fairly contentious, e.g. DotNetAnalyzers/StyleCopAnalyzers#2416, with rationale added in DotNetAnalyzers/StyleCopAnalyzers#2418.

@sharwell I see from the code it works for object, array, and collection initializers. Does that apply to enumeration declarations as well?

[sharwell]

@heaths As of DotNetAnalyzers/StyleCopAnalyzers#2239 it does 😄

Closing as external. StyleCop handles this.
