Subject: Only check src/ directory for whitespace errors in the pre-commit
 hook

This allows importing of external libraries into externals/ without
having to reformat them. Unfortunately it also allows whitespace to be
introduced in files like the root CMakeLists.txt, but that is a small
downside compared to the tradeoff.

 If you know what you are doing, you can try 'git commit --no-verify' to bypass the check.
