> Suggest to add a simple csh like command line history.
> * A new command "history" is added to the Shell class listing the command history
> * A new History class is added to manage a bounded, in-memory-only command history
> * Commands can be reused from the history using commands following this simple syntax:
>          command = ( '!' spec ) | ( '^' subst ) .
>          spec = '!' event [ ':' [ 'a' | 'g' ] 's' regex ] .
>          event = ( '!' | idx | '?' find | string )
>          idx = [ '-' ] { 0..9 } .
>          find = string ( '?' | EOL ) .
>          subst = pat '^' repl '^' EOL .
>          regex = str pat str repl str EOL .
