Style enforcing code.

== How to reproduce the binaries at <https://dev-www.libreoffice.org/bin/> ==

- Linux:

  - Built from source on openSUSE Leap 42.3
  - get <http://releases.llvm.org/5.0.0/llvm-5.0.0.src.tar.xz>
  - get <http://releases.llvm.org/5.0.0/cfe-5.0.0.src.tar.xz>  and extract this as tools/clang/ in the LLVM source code
  - mkdir workdir; cd workdir; cmake -G 'Unix Makefiles' -DCMAKE_INSTALL_PREFIX=$PWD/../instdir -DCMAKE_BUILD_TYPE=Release -DLLVM_BUILD_STATIC=true ..; make -j8 clang-format
  - this produces a binary that is statically linked

- macOS:

  - <http://releases.llvm.org/5.0.0/clang+llvm-5.0.0-x86_64-apple-darwin.tar.xz> provides a portable binary already

- Windows:
