git-sh-setup one is easy to fix.  We could say something equally
silly like this instead:

The only thing that code cares about is to use a relatively
cheap command to examine "$GIT_DIR/config" to make sure that the
respository format version recorded in the file is of old enough
vintage we understand; the command to cause .git/config to be
read does not have to be git-var.

So after nixing that one, the remaining users all look like they
do want something reasonable from the user anyway, so for them
git-var that fails when the user has not fixed the unusable
gecos is a desirable thing.

	git grep -n git-var '*.sh'

shows:

git-am, git-applypatch, git-format-patch::
	use it to add sign-off by the user.

git-commit, git-tag::
	use it to record the user identity.

git-pull::
	this uses git-var-l which is unfortunate.  We should
	be able to use git-repo-config instead.  Patches
	welcome.
