After discussion among developers we settled on the Mozilla style
with a few tweaks:
* Do not align operator arguments.
* Do not always break after a function return type.
* Limit to 79 columns instead of 80 to fit edge cases
better in 80-column terminals as CMake has always done.
* Format for C++98 instead of C++11 because CMake is written
in the former language.
