docs: This method is like {@link #getFormatter(String, String)} but reads the
  {@link AbstractNlsFormatterPlugin#getStyle() style} from the given scanner.
  
  @param formatType is the type to be formatted.
  @param scanner is the current {@link CharSequenceScanner} for parsing the style defining details of formatting.
  @return the according {@link NlsFormatter}.
