+Tips to prevent and resolve:
+* Enable WITH_ASTYLE in your cmake configuration
+* Use scripts/astyle.sh file to fix the now badly indented files
+* Consider using scripts/prepare-commit.sh as pre-commit hook to avoid this
+  in the future (ln -s scripts/prepare-commit.sh .git/hooks/pre-commit) or
+  run it manually before each commit.
