Follow-up Comment #12, bug #51151 (project findutils):

I've read the discussion but I don't understand what's wrong with this

git grep -l -z foo | xargs -0 sh -c 'jupp "$@" < /dev/tty' jupp

This doesn't need "xargs -o" and is not specific to any shell implementation. 
 There is talk in this bug report about problems with "sh -c ... --" but that
construct ("--") is not used or needed.

So, can someone please explain what's wrong with "</dev/tty"?
