    sh(1): make it the default shell for the root user
    
    In the recent history sh(1) has gain the missing features for it to
    become a usable interractive shell:
    - command completion
    - persistent history support
    - improvements on the default bindings in emacs mode
    - improvements in the vi mode (repect $EDITOR)
    - print a newline when exiting via ^D
    - default prompt and improvements on how PS1 can be configured
    - and more.
    
    This changes also simplifies making tiny freebsd images with only sh(1)
    as a shell
