Skip timestamp differences for diff --no-index
We display empty diffs for files whose timestamps have changed. Usually, refreshing the index makes those empty diffs go away. However, when not using the index they are not very useful and there is no option to suppress them. This forces on the skip_stat_unmatch option for diff --no-index, suppressing any empty diffs. This option is also used for diffs against the index when "diff.autorefreshindex" is set, but that option does not apply to diff --no-index.
