C++ 叮当声格式：IncludeIsMainRegex不起作用

我在查找源文件的主包含时遇到问题。但是一步一步

文件z.h

#include "test"
#include "azd"
#include <vector> 
#include <boost/something>
#include <map>

#包括“测试”
#包括“azd”
#包括
#包括
#包括

文件z.C

#include "test"
#include "azd"
#include <vector>
#include <boost/something>
#include <map>
#include "z.h"

#包括“测试”
#包括“azd”
#包括
#包括
#包括
#包括“z.h”

文件（部分）.clang格式与z.h和z.C位于一起

BasedOnStyle: LLVM
Language: Cpp
IncludeIsMainRegex: '(_test)?$'
IncludeCategories:
- Regex:    '^(<boost)'
  Priority: 3
- Regex:    '^<'
  Priority: 4
- Regex:    '.*'
  Priority: 1

BasedOnStyle:LLVM
语言：Cpp
IncludeIsMainRegex:“（_测试）？$”
IncludeCategories：
-正则表达式：“^（看起来，在您的情况下，当源文件具有
*.C
扩展名时，唯一不起作用的是
IncludeIsMainRegex
选项

如果我没有错，那么这个选项只对源代码文件进行工作，这些文件有<代码> *.c、*.cc、*.cp、*.C++、*.cxx < /c>扩展> 
我的假设基于
clang（v7.0.0）
文件
clang/lib/Tooling/includes/HeaderIncludes.cpp中的这段代码：
