Yuri Kunde Schlesner 37319fb17f 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.

Error: This commit would contain trailing spaces or tabs, which is against this repo's policy.
Please correct those issues before commiting. (Use 'git diff --check' for more details)
If you know what you are doing, you can try 'git commit --no-verify' to bypass the check
