From 88913c0139ac6d1dfb356d3048702b7bc8ef4079 Mon Sep 17 00:00:00 2001

Subject: ALL: Remove trailing whitespaces

This tries to make our code a bit more compliant with our code formatting
conventions. For future use, this is the command I used:
  git ls-files "*.cpp" "*.h" | xargs sed -i -e 's/[ \t]*$//'
