[PATCH] Add support for foreach macros to clang-format

[Daniel Jasper]

  1. I don't.
  2. How would you verify that your regex addresses all of those 500 macros.
  3. If you are loose enough, how do you guarantee that you don't also include a function that is not a foreach macro?
  4. Are there really 500 different foreach macros? I couldn't come up with that many different ways of spelling it.
