- supplying <init-files> for --r6rs-script or --script now raises an

error (as suggested by Derick Eddington).
- The -h or [-b <bootfile>] options must now come first, so,
  the rest of the command-line arguments are not scanned: only the
  first one or two.   The docs (in ikarus -h) already suggested the
  correct invocation arguments, so, this conforms to the previously
  documented behavior.
