Subject: force no-tab/trailing spaces with git hook

Remove unneeded stuff from pre-commit script

The check against an empty commit was not needed (it is only a security for the 1st commit after git init).
It could also possibly pose problems because of the redirection to /dev/null on some windows systems.

newline at EOF & fixed indent
