[perl #113954] [BUG] Usage message suggests unquoted way of passing several-word argument which will not work in Rakudo

$ perl6 -e 'multi MAIN("foo bar") {}' foo bar
Usage:
  -e '...' foo bar
$ perl6 -e 'multi MAIN("foo bar") { say "OH HAI" }' 'foo bar'
OH HAI
$

The usage message is confusing because it suggests exactly the
sequence of arguments that failed and triggered the message.
Shell-quoting the two words makes the invocation succeed. I suggest
the shell-quoting be included in the usage message -- but the exact
nature of the fix doesn't matter that much to me, the most important
thing is that usage message not suggest things that don't work.
