Hello,
‘vc-git-root’ as found in Emacs 24.2.1 is too lax: when called from a
non-Git directory under $HOME, it ends up returning ~/ because users
normally have a ~/.git directory holding a config file.
A better definition would be something like this:

Thanks,

I did, but now I realize that ~/.gitconfig is what matters nowadays (or
maybe ~/.git/config never mattered, even.)
Sorry for the noise.

Beside the fact that ~/.git is not the config directory, the above code
has some problems:
vc-git.el uses lexical-binding, so using lexical-let in it is a bad idea.
file-in-directory-p sounds completely wrong here. You want to use
(file-directory-p (expand-file-name "objects" root)) instead.
And of course you could have used simply (vc-find-root file ".git/objects").

That is not right. .git in a git root directory might be a regular
file.
