Previous one warned people upfront to encourage fixing their environment early, but some people just use repositories and git tools read-only without making any changes, and in such a case there is not much point insisting on them having a usable ident. This round attempts to move the error until either "git-var" asks for the ident explicitly or "commit-tree" wants to use it. Signed-off-by: Junio C Hamano <junkio@cox.net>
