You can easily convert the string "$1" to a token stream, however, there
is no fully robust way to translate that token stream into a list of
commands without reimplementing the parser.

Just consider the following cases (there are more, but you should get
the gist):

    # quoted semicolon
    echo lorem\;ipsum

    # non-top-level semicolon
    (foo; bar); baz
    () { foo; bar } baz
    for 1 in foo bar; baz $1

    # non-semicolon
    foo& bar& 
    case foo in (bar) : ;; esac

    # INTERACTIVE_COMMENTS
    echo foo # bar ;

What are you trying to do now?  This is no longer your original
question about recording the hostname in history.

Is this about 'rap' being called in the middle of a command line…?

Cheers,
