Tips to prevent and resolve:
* Enable WITH_ASTYLE in your cmake configuration to format C++ code
* Install autopep8 (>= 1.2.1) to format python code
* 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.
