The style guide doesn't mention indenting designated initializers with 2 spaces?

Looks like this patch doesn't put the opening brace at the outerscope for some of the examples from the linked github issues:

$ cat .clang-format
AllowShortLambdasOnASingleLine: None
BraceWrapping:
  BeforeLambdaBody: true
BreakBeforeBraces: Custom
LambdaBodyIndentation: OuterScope
$ cat test.cpp
aaaaaaaaaaaaaaaaaaaa(1,
	             b(
	             	[]
                     {
                       return 0;
                     }));

some_function(a_really_long_name, another_long_name, a_third_long_name,
              [&](LineCallback line_callback)
{
  int a;
  int b;
});
$ clang-format test.cpp
aaaaaaaaaaaaaaaaaaaa(1, b(
                            []

                              return 0;
                            }));

some_function(a_really_long_name, another_long_name, a_third_long_name,
              [&](LineCallback line_callback)
              {
                int a;
                int b;
              });
$ 

Shouldn't the expected output be the same as the input?

All comments addressed so bump on review please :)

Please see https://clang.llvm.org/docs/ClangFormatStyleOptions.html#adding-additional-style-options. Is there a way to fix the issue without adding a new option?

Change DesignatedInitializerIndentWidth to a signed integer which defaults to ContinuationIndentWidth when set to -1.

Update OuterScope docs in Format.h and regenerate public docs.

The previous implementation of the option involved a hack which corrupted the parenthesis state stack.

Can you link the review (e.g. Dnnnnnn) of the previous implementation in the summary?

Specifically, this change fixes github issues #55708, #53212, #52846 and #59954.

Please link the issues (e.g. https://github.com/llvm/llvm-project/issues/nnnnn).

Apply clang-format.

Add new code sample to demonstrate behaviour of "LambdaBodyIndentation: OuterScope"
