Your script still has the printf bug, you should do printf "%s" "stuff" whenever the input is a variable. You also use unquoted strings in a number of places.
As you consider your script a teaching script, it is really doing people a disservice to teach them these bad habits, and the longer you put off fixing it, the harder it will be to do.

git-sh-i18n
GIT-SH-I18N(1) Git Manual GIT-SH-I18N(1)
NAME
git-sh-i18n - Git's i18n setup code for shell scripts
SYNOPSIS
. "$(git --exec-path)/git-sh-i18n"
DESCRIPTION
This is not a command the end user would want to run. Ever. This documentation is meant for people who are studying the Porcelain-ish
scripts and/or are writing new ones.
The 'git sh-i18n scriptlet is designed to be sourced (using .) by Git's porcelain programs implemented in shell script. It provides
wrappers for the GNU gettext and eval_gettext functions accessible through the gettext.sh script, and provides pass-through fallbacks on
systems without GNU gettext.
FUNCTIONS
gettext
Currently a dummy fall-through function implemented as a wrapper around printf(1). Will be replaced by a real gettext implementation in
a later version.
eval_gettext
Currently a dummy fall-through function implemented as a wrapper around printf(1) with variables expanded by the git-sh-
i18n--envsubst(1) helper. Will be replaced by a real gettext implementation in a later version.
GIT
Part of the git(1) suite
