There are two issues in that logic.

The git-sh-setup API is a published interface that third-party Porcelains
can use, so it is insufficient to audit only the in-tree code.

Besides, your audit of in-tree code is insufficient. See output from this:

    $ git grep -A1 -n -e 'die .*\\$' -- '*.sh'

The hits in git-bisect.sh and git-rebase--merge.sh both pass two strings.

Can't you instead introduce a new "die_with_status" function and use it?
