Problem with BufferedInputStream

[Steve Ratcliffe]

There is a problem with the one argument read method of
BufferedInputStream.  It goes directly to the underlying file rather
than reading out of the buffer. For example:

	FileInputStream fis = new FileInputStream("foo");
	BufferedInputStream is = new BufferedInputStream(fis);
	c = is.read();  // Fill the buffer and read first byte.
	is.read(b);	// Wrong bytes read here; gets correct bytes
				// without preceeding line

The real problem is in the underlying FilterInputStream method I think.
The one arg method should call the three arg method.  (This change
then requires that the 3 arg method be used in the BufferedInputStream
constructor)

A possible fix follows.
