I wrote it up just for fun, and here's the patch. I'll leave it up to you
to decide if it's worth it.

First, though, I've got another patch to --dirstat, which - in the case
of renames, attributes the damage to the target filename instead of the
source filename. I found this more intuitive, especially in the case of
copies (-C -C) where damage would be attributed to the directory
containing the (unchanged) source file, instead of the directory
containing the (changed) target file.


Have fun! :)
