[PATCH] Fix handling of negative suffix in DecimalFormat

When a negative subpattern is not explicitly defined,
DecimalFormat was not using the positive suffix for
negative values.

Simple test case to reproduce the problem:

  DecimalFormat tempFormat = new DecimalFormat("0.0 unit");
  System.out.println(tempFormat.format(4.3));
  System.out.println(tempFormat.format(-4.3));

Yields:

4.3 unit
-4.3
