IndentPPDirectives: AfterHash

In a fragment:

#pragma once
#ifndef HEADER_ID_H
#define HEADER_ID_H // (1)

clang-format inserts indent in (1) after the hash sign

In a fragment:

#pragma once
#ifndef HEADER_ID_H
#define HEADER_ID_H // (1)

clang-format inserts indent in (1) after the hash sign

Doesn't the pragma make the header guard redundant and vice versa? Anyway, clang-format checks for header guards only at the beginning of the input as it's supposed to.
