> CSVFormat.format trims last delimiter if the delimiter is a white space

> Key: CSV-211

> Issue Type: Bug
> Affects Versions: 1.4

> The function CSVFormat.format() trims off the last delimiter if the delimiter
> is a white space character and the value in the last column is null.
> {code:java}
> public String format(Object... values) {
> StringWriter out = new StringWriter();
> try {
> (new CSVPrinter(out, this)).printRecord(values);
> return out.toString().trim();
> } catch (IOException var4) {
> throw new IllegalStateException(var4);
> }
> }
> {code}
> For example, consider the following records (\t = tab)-
> ID{color:red}\t{color}Name{color:red}\t{color}Country{color:red}\t{color}Age
> 1{color:red}\t{color}John Doe{color:red}\t{color}USA{color:red}\t{color}20
> 2{color:red}\t{color}Jane Doe{color:red}\t{color}USA{color:red}\t{color}
> The CSVFormat.format() on both the rows returns the following -
> ID{color:red}\t{color}Name{color:red}\t{color}Country{color:red}\t{color}Age
> 1{color:red}\t{color}John Doe{color:red}\t{color}USA{color:red}\t{color}20
> 2{color:red}\t{color}Jane Doe{color:red}\t{color}USA
> Note that there is a missing delimiter for the last column in the second
> record.
> This usually causes schema mismatch when we try and read back the CSV file as
> there is one less column in all the rows which have a null at the end.
> I feel the trim() is unnecessary while returning *out.toString()*
