[PATCH 2/3] ident.c: check explicit identity for name and email separately

From
Junio C Hamano <gitster@pobox.com>

bb1ae3f (commit: Show committer if automatic, 2008-05-04) added a logic to check both name and email were given explicitly by the end user, but it assumed that fmt_ident() is never called before git_default_user_config() is called, which was fragile. The former calls setup_ident() and fills the "default" name and email, so the check in the config parser would have mistakenly said both are given even if only user.name was provided.

Make the logic more robust by keeping track of name and email separately.
