Both culix and joshwa have great answers. If you name your heroku git remotes the same as your corresponding heroku apps you can have an even shorter and more robust .git/hooks/pre-push hook:

#!/bin/bash

remote="$1"
url="$2"

if [[ $url =~ heroku ]] ; then
    hash_name=COMMIT_HASH
    hash=$(git rev-parse HEAD)
    echo Setting $hash_name to $hash on app $remote
    heroku config:set $hash_name=$hash --app $remote
fi

exit 0
