Can I configure git so it does not guess user.email configuration settings?

Question

On my system I don\'t have the user.email git configuration value set at the global level, on purpose. Instead, I configure it individually in each sandbox. This is

The pre-commit solutions proposed here work well and I will accept one of them. I ended up using this:

if [ -z $(git config user.email) ]; then
    echo "You need to set your user.email configuration value for this project"
    echo "git config user.email foo@example.com"
    exit 1
fi

It gets activated system-wide in my ~/.gitconfig file with the init.templatedir config value, which I saw mentioned in another Stack Overflow post. I put my template dir on github as part of my git-tools collection.

Additionally, I realized that I can also just perform a check in my shell prompt logic, which already adds git status to the prompt, to print a big, fat warning when I cd into a sandbox that does not have the user.email value configured.

In my .bashrc:

PS1='\u@\h:\W$(parse_git_branch) \$ '

parse_git_branch() {
    local DIRTY STATUS EMAIL_NOT_CONFIGURED_WARNING
    STATUS=$(git status 2>/dev/null)
    [ $? -eq 128 -o $? -eq 127 ] && return
    [ -z $(git config user.email) ] && EMAIL_NOT_CONFIGURED_WARNING=$' \x1b[31m(user.email not configured)\x1b[m'
    [[ "$STATUS" == *'working directory clean'* ]] || DIRTY=' *'
    echo "($(git branch 2>/dev/null | sed -e '/^[^*]/d' -e 's/* //')$DIRTY)$EMAIL_NOT_CONFIGURED_WARNING"
}

This produces an easily visible warning:
