I am still looking at the code in ref-filter.c these two days, I deeply
doubt whether we can add a --no-sort option to git for-each-ref,

Inspired by Peff's experimental patches [1], I think the --no-sort option
may improve the performance of ref-filter by avoiding the execution
of ref_array_sort().

I don't know if this can be regarded as a micro-project.

This may require the help of this patch of mine: [2]
which use list api for ref_sorting. This may can help eliminate unnecessary
sorting.

Thanks.
