Broken VirtualRoot.Entry.outputStream()

[DavePearce]

The following method in wyfs.util.VirtualRoot.Entry is broken:

public OutputStream outputStream() {
            lastModified = System.currentTimeMillis();
            data = new byte[0];
            // create an output stream which will automatically resize the given
            // array.
            return new OutputStream() {
                private int pos = 0;

                public void write(int b) {
                    if (pos >= data.length) {
                        data = Arrays.copyOf(data, (data.length + 1) * 2);
                    }
                    data[pos++] = (byte) b;
                }
            };
        }

It's broken because it leaves empty bytes at the end of final array.
