Comment (by eschnett):

 Since the global .clang-format file doesn't work, the option to use seems
 to be:
 {{{
 clang-format -style="{BasedOnStyle: LLVM, Standard: Cpp03}"
 }}}

 Unfortunately, it seems that different clang-format versions make slightly
 different decisions regarding how to break lines or how to interpret
 ampersand characters. (The latter are difficult to interpret if one
 doesn't have full type information.) It thus seems that re-formatting
 everything with different versions of clang-format leads to changes.

 I'm using clang-format 3.7, the latest released version. Clang is
 relatively easy to install (easier than GCC), and we should be able to
 decide on a single version for the Einstein Toolkit. For example, Ubuntu
 LTS currently provides version 3.6.
