ZSH: Makes prompt shorter in narrow terminals

This is mainly achieved by no longer showing the full path.

If the terminal is less than 100 characters, it will show a preceding
icon, >> then the bottom most folder name.

The >> indicates that folders have been missed.

I have added an icon for my dotfiles folder
