In clang-format 12, `CompactNamespaces` misformatted the code when `AllowShortLambdasOnASingleLine` is set to false and `BraceWrapping.BeforeLambdaBody` is true.
Input:
```
namespace out {
namespace in {
}
} // namespace out::in
```
Expected output:
```
namespace out { namespace in {
}} // namespace out::in
```
Output from v12:
```
namespace out {
namespace in {
}
} // namespace out::in
```
Config triggering the issue:
```
---
AllowShortLambdasOnASingleLine: None
BraceWrapping:
BeforeLambdaBody : true
BreakBeforeBraces: Custom
CompactNamespaces: true
...
```
Seems there's a corner case when `AllowShortLambdasOnASingleLine` is false, and `BraceWrapping.BeforeLambdaBody` is true, that causes CompactNamespaces to stop working.
The cause was a misannotation of `{` opening brace after `namespace` as a lambda opening brace.
The regression was probably introduced with [this commit](

//===----------------------------------------------------------------------===// // C Language Family Front-end //===----------------------------------------------------------------------===// Welcome to Clang. This is a compiler front-end for the C family of languages (C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM compiler infrastructure project. Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source-level tools. One example of this is the Clang Static Analyzer. If you're interested in more (including how to build Clang) it is best to read the relevant web sites. Here are some pointers: Information on Clang: http://clang.llvm.org/ Building and using Clang: http://clang.llvm.org/get_started.html Clang Static Analyzer: http://clang-analyzer.llvm.org/ Information on the LLVM project: http://llvm.org/ If you have questions or comments about Clang, a great place to discuss them is on the Clang development mailing list: http://lists.llvm.org/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
