Support 'master@2 hours ago' syntax
Extended sha1 expressions may now include date specifications which indicate a point in time within the local repository's history. If the ref indicated to the left of '@' has a log in $GIT_DIR/logs/<ref> then the value of the ref at the time indicated by the specification is obtained from the ref's log. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
