Thanks for this insight. I ended up using `git ls-files` and `--ignored` to print out all the files that I want to ignore, and I converted that into a `find` exclusion list.

Here is the final command: $ git ls-files --others --ignored --exclude-standard --directory | (printf "%s\n" $ -path ./.git; sed -e 's/^/.\//' -e 's/\/$//' -e 's/^/-o\n-path\n/'; printf "%s\n" $ -prune -o ! -type d -print0 ) | xargs --exit find . | xargs -0 --max-procs 0 cp --parents --no-dereference -t /tmp/clone

This is actually a lot faster than I would have expected. Parallelizing the `cp` cuts the time down dramatically.

Thanks again!

p.s., Sorry for the resend. I forgot to send a plain text to the mailing list.
