Pre-commit hook/Run check_po whenever we try to commit a po file in all Git repositories

Currently, contribute/l10n_tricks/check_po.sh calls i18inspector and executes some checks. However, it does not check for inconsistent line endings and the like. We should fix that by looking at “git log -p *.po” and determining the manual fixes we regularly do.
