<pre>
    Consider the file `test.cpp`:
```C++
class Foo{
         void test() {
#define A \
int aaaa; \
int b; \
int dddddddddd;
  }
};
```
The `.clang-format` file contains only 
```
IndentPPDirectives: None
```
Running `clang-format.exe ./test.cpp --lines=5:5`, where line 5 is the one with `int b` results in
```C++
class Foo{
         void test() {
#define A \
         int aaaa; \
         int b; \
         int dddddddddd;
 }
};
```
I.e. the macro body gets aligned with `void test()`. The expectation is that the macro body has an indent of 2 spaces:
```C++
class Foo {
  void test() {
#define A \
  int aaaa; \
  int b; \
 int dddddddddd;
  }
};
```

I noticed that while working on [D151047](https://reviews.llvm.org/D151047) and shortly debugged into: In `LevelIndentTracker::nextLine()`, the code calls `getIndent(Line.Level)` when formatting the macro because of `PPDIS_None` (see [here](https://github.com/llvm/llvm-project/blob/9b9848fb4d04fb8d341c5035595c1531b7bd36e0/clang/lib/Format/UnwrappedLineFormatter.cpp#L65-L78)). The `Level` of the macro body is 1. `LevelIndentTracker::IndentForLevel[Level=1]` contains the indent of the `void test()` line. Hence the wrong indent.

>From what I could gather, `LevelIndentTracker::IndentForLevel` should **never** be used when formatting PP directives. `LevelIndentTracker::IndentForLevel` appears to be for non-PP code only?
