    sample code using stringize operator (`#`)

```c
// Allow the command line to specify a "profile" file
#if 1
#define PROFILE_QUOTE(IDxxxX)   #IDxxxX
#define PROFILE_INCLUDE(abcdef) PROFILE_QUOTE(abcdef)
#endif

#define PROFILE_QUOTE2(IDxxxX)   #IDxxxX
#define PROFILE_INCLUDE2(abcdef) PROFILE_QUOTE2(abcdef)
```
clang-format command & version
```
c:\clangerror>clang-format --version
clang-format version 12.0.0

c:\clangerror>clang-format --style="{IndentPPDirectives: AfterHash, WhitespaceSensitiveMacros: ['PROFILE_QUOTE', 'PROFILE_QUOTE2']}" sample.h
```

result:
```
// Allow the command line to specify a "profile" file
#if 1
#  define PROFILE_QUOTE(IDxxxX) #  IDxxxX
#  define PROFILE_INCLUDE(abcdef) PROFILE_QUOTE(abcdef)
#endif

#define PROFILE_QUOTE2(IDxxxX) #IDxxxX
#define PROFILE_INCLUDE2(abcdef) PROFILE_QUOTE2(abcdef)
```
Expected:
`PROFILE_QUOTE` is indented under the `#if`, but the actual definition of the macro `#IDxxxX` is untouched.

I understand the intent of WhitespaceSensitiveMacros to NOT modify the DEFINITION of the macro.  Please let me know if I misunderstand the purpose, thanks.
