git log -z doesn't separate commits with NULs

Hello all.

I wanted to generate several files with some statistics using "git log -z" command. I did something like this: git log -z --patch HEAD~10..HEAD -- SomePathHere | xargs -0 --max-chars=1000000 ~/1.sh

If I put echo "started" into the file ~/1.sh I see that the file is called only once instead of multiple times.

I'm newbie to xargs, thus I tested with and that worked as I expected. find . -type f -print0 | xargs -0 ./1.sh That produced a lost of "started" lines.

Thus I suspect there is a but in git log -z command and that doesn't "Separate the commits with NULs instead of with new newlines." as promised in the documents. Is my understanding correct or I don't understand the documentation or somehow pass wrong parameters into git log?

Thank you. Best regards, Nikolaj
