Add Root checking and dispalying

[athul]

Closes #33

@Micha-Btz could you try it out on your system?

[Micha-Btz]

Yes I will test it tonight. Thanks a lot.

Seems to work only in the home directory from root.

My intention was to have always root in the prompt as it is on a Debian default machine, equal if logged in as root or changed to root via sudo or su. I should had it described more precise.

> 🐭 ~/source/go/src
> ❯ su
> Passwort: 
>  /home/mdomann/source/go/src
> ❯ cd 
>  root ~
> ❯ ls
> dotfiles  Release.key
>  root ~
> ❯ cd /etc/
>  /etc on  master [1!] 
> ❯ cd
>  root ~
> ❯ cd /usr/
>  /usr
> ❯ cd /var
>  /var
> ❯

@Micha-Btz could you check now?

[Micha-Btz]

hey,
I think it's working now.

root ~/var
cd
root ~/root
cd /usr/
root ~/usr

For optical reason it will be cool the tilde ~ is only used in the home of root and would be not displayed in other paths.

Thanks.

Could you test now

[Micha-Btz]

❯ cd
root at ~
❯ cd /var/
root at /var
❯ cd /etc/
root at /etc
❯ cd
root at ~

Seems that working in git is not showing anymore:

 ~/source/shelby on  master [3!][1+] 
❯ cd
 ~
❯ su

 root at /home/mdomann

[Micha-Btz]

❯ cd /etc/
 root at /etc

Damn, New Changes tend to bring up new shortcomings. I'll look more into it
