am: shorten ident_split variable name in get_commit_info()

The local ident_split variable is often mentioned three times per line when dealing with its begin/end pointer pairs. Let's use a shorter name which lets us get rid of some long lines. Since this is a short self-contained function, readability doesn't suffer. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
