allow for changing the current directory on exit

For this to work you'll need to put this in your ~/.zshrc (or equivalent rc file):

lg()
{
    export LAZYGIT_NEW_DIR_FILE=/Users/jesseduffieldduffield/Library/Application\ Support/jesseduffield/lazygit/.lastd

    lazygit "$@"

    if [ -f $LAZYGIT_NEW_DIR_FILE ]; then
            cd "$(cat $LAZYGIT_NEW_DIR_FILE)"
            rm -f $LAZYGIT_NEW_DIR_FILE > /dev/null
    fi
}
