My new Git pre-commit hook

This appears to be kind of useful:

#!/bin/sh

output=$(find . -name '.#*' -print)
if [ -n "$output" ]; then
        echo "unsaved Emacs files:" 1>&2
        echo "$output" 1>&2
        exit 1
fi

Had that kind of problem a few times. :-)

Now what would be really handy are system-wide Git hooks that apply to all repositories, like ~/.gitignore complements .git/info/exclude.
