Originally the code was from django.utils.text.recapitalize, but it was removed in https://github.com/django/django/commit/b4a11f2720fbbb47f7c03a5a00b3cfb334266a92
So I decided to save it here. But I modified it because originally the function is too dumb: https://code.djangoproject.com/ticket/21651
