Nico Weber 7533b4dada clang-format: Don't let -style=Chromium imply c++03 template formatting.

Daniel Jasper 540dbe29bc clang-format: Prevent column layout if elements aren't uniform enough.
This patch only considers the difference between the length of the
shortest and longest element, but we might want to look at other
features (token count, etc.) in future.

Roman Kashitsyn 650ecb53ca Fix bug 20892 - clang-format does not handle C-style comments
Summary:
http://llvm.org/bugs/show_bug.cgi?id=20892

Add support of C-style formatting enabling/disabling directives. Now the following two styles are supported:

  // clang-format on
  /* clang-format on */

The flexibility in comments (support of extra spaces and/or slashes, etc.) is deliberately avoided to simplify search in large code bases.

Roman Kashitsyn a043cedf0a Fixes bug 20587 - Add K&R break before braces style
Summary:
http://llvm.org/bugs/show_bug.cgi?id=20587

Added K&R style. It could be enabled by the following option:

```
BreakBeforeBraces: KernighanRitchie
```

This style is like `Attach`, but break *only* before function
declarations.

As I can see, no additional logic required to support this style, any
style different from other styles automagically satisfies K&R.
