Unsetting HOME is an easy way to skip what is in ~/.gitconfig when
helping other people on this list, and I wouldn't mind such a
warning while I knowingly unset it, I can imagine other helpful
people may find such a warning irritating and complain "I know I do
not have $HOME set, as I earlier explicitly did unset it myself!".

So, I am on the fence on this one, but because

 (1) no warning would mean upstart scripts writers need to be aware
     of lack of $HOME, but they need to be aware of it for reasons
     unrelated to Git anyway; and

 (2) a warning while trying vanilla Git behaviour to help others
     might be irritating, it is not an every day use anyway.

I do not think it matters either way in practice.
