title: CSVPrinter quotes the value even when it does not have a delimiter or line separator
body: <p>When CSVFormat's quoteMode is set to MINIMAL, it should quote the value only when the value contains a delimiter (,) or line separator '\n' according to the <a href="https://commons.apache.org/proper/commons-csv/archives/1.4/apidocs/index.html" rel="nofollow">javadoc</a>.
  But it does quoting even if the value contains hash (#). Please see below example code</p>
  
  <pre><code>  @Test
    public void testCSV() throws IOException {
      String[] row = new String[]{"simple text","##5##"};
      CSVFormat CSV_FORMAT = CSVFormat.DEFAULT.withRecordSeparator("\n").withQuoteMode(QuoteMode.MINIMAL);
  
      StringWriter stringWriter = new StringWriter(1024);
      CSVPrinter csvPrinter = new CSVPrinter(stringWriter, CSV_FORMAT);
      csvPrinter.printRecord(row);
      System.out.println("sw : " + stringWriter.getBuffer().toString());
      csvPrinter.close();
      stringWriter.close();
    }
  </code></pre>
  
  <p><strong>output</strong> :  sw : simple text,"##5##"</p>
  
  <p>Please suggest a way in which I can avoid quoting in such cases.</p>
