            Bug ID: 48581
           Summary: requires-expression braces and requirement-seq aren't
                    indented, constraint-expression further indented
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Formatter
          Assignee: unassignedclangbugs at nondot.org
          Reporter: johelegp at gmail.com

.clang-format:
```yaml
```

Input and expected formatted result:
```C++
/*export*/ template <class T>
concept relative_quantity_field =
  absolute_quantity_field<T> and std::same_as<T, relative_quantity_t<T>> and
  requires(const T &c, T &l, const rep_t<T> &r) //
  {
    { l *= r } -> std::same_as<T &>;
    { l /= r } -> std::same_as<T &>;
    { c *r } -> std::same_as<T>;
    { r *c } -> std::same_as<T>;
    { c / r } -> std::same_as<T>;
    { c / c } -> std::same_as<rep_t<T>>;
  };
```

Actual output:
```C++
/*export*/ template <class T>
concept relative_quantity_field =
    absolute_quantity_field<T> and std::same_as<T, relative_quantity_t<T>> and
    requires(const T &c, T &l, const rep_t<T> &r) //
{
  { l *= r } -> std::same_as<T &>;
  { l /= r } -> std::same_as<T &>;
  { c *r } -> std::same_as<T>;
  { r *c } -> std::same_as<T>;
  { c / r } -> std::same_as<T>;
  { c / c } -> std::same_as<rep_t<T>>;
};
```

The _constraint-expression_ has an extra indentation, for 4 spaces instead of
the default 2. The _requirement-seq_ and braces of the _requirement-expression_
are missing such an extra indentation.
