Bad indent for anonymous field types with trailing comma #42

pub const St = struct {
    anon_field: enum {
    },
};

pub const St = struct {
    anon_field: enum {
},
};

pub const St = struct {
    anon_field: enum {
        some_field
    }, // indents properly
};

// if there is no trailing comma, it indents properly
pub const St = struct {
    anon_field: enum {
        some_field
    }
};

// if there is any character other than a comma after the line, it also indents properly
pub const St = struct {
    anon_field: enum {
    }, // this comment prevents the indent problem
};
pub const St = struct {
    anon_field: enum {
    }, 
    // (there's a trailing whitespace on the line above)
};

// empty lines do not solve the problem
pub const St = struct {
    anon_field: enum {

},
};

// identifiers that are on the same line as the opening bracket do not solve the issue either.
pub const St = struct {
    anon_field: enum { foo, bar
},
};
pub const St = struct {
    anon_field: enum { foo, bar,
        a // it solved with this one here, though
    },
};

// it also happens with `struct` and any other type. The problem seems to be on the brackets themselves.
