Wrong or unchanged indentation when initializing structs.

Bug type: Language Service

With VSCode 1.56 (April 2021) & cpptools 1.4.1

There are problems with the indentations of struct initializers.

• When initializing a variable, the indentation is unchanged.
• When returning, the indentation is changed but wrong.
  • The first line is correct.
  • The rest is double-indented.

typedef struct thing {
    int a;
    int b;
} thing;

thing get_thing() {

    /* In these situations: indentation is unchanged */
    thing a = {
            10, // wrong indentation not corrected
    10 // wrong indentation not corrected
    };
    thing t = {
                .a = 10, // wrong indentation not corrected
    .b = 10 // wrong indentation not corrected
    };
    t = (thing){
        .a = 10, // had to manually indent those ones
        .b = 10 // indentation is unchanged by formatter
    };

    /* In these situations: indentation is worng */
    return (thing) {
        .a = 10, // good
            .b = 10 // wrong indentation formatted
    };
}

Configuration:

"C_Cpp.formatting": "vcFormat"
"C_Cpp.vcFormat.indent.caseLabels": true

Reproduce the issue using the embedded C struct-initializer example with C_Cpp.formatting set to vcFormat and the listed indentation setting. Trace the vcFormat handling for variable initialization and return expressions, then verify that the resulting indentation matches the example's expected layout.
