I can not specify an other formater or a style guide that uses this style. The
problem is that clang-format is rather destructive at this point. Other
formatters like astyle or the one from CLion keep empty lines after an access
modifier. The behavior of clang-format before this patch was to remove all
empty lines after an access modifier. The option `MaxEmptyLinesToKeep` is
currently ignored at this point.
After thinking a little bit about this:
If the removal of all lines after an access modifier is rather a bug than a
feature, then the change:
if (PreviousLine && PreviousLine->First->isAccessSpecifier() &&
(!PreviousLine->InPPDirective || !RootToken.HasUnescapedNewline))
- Newlines = std::min(1u, Newlines);
+ Newlines = std::max(1u, Newlines);
if (Newlines)
would solve this problem.

Yes. I will change this in the next update.

I can change this, but the current output of the tests is (I forced the error):
```
/<path>/llvm-project/clang/unittests/Format/FormatTest.cpp:72: Failure
Expected: Expected.str()
Which is: "class Foo {\nprivate:\n\n int i;\n};"
To be equal to: format(Expected, Style)
Which is: "class Foo {\nprivate:\n int i;\n};"
With diff:
@@ -1,5 @@
class Foo {
private:
-
int i;
};
```
Which is actually human readable in this case. Shall I still change it?
