In the test1.Rnw file, your \SweaveOpts statement spans two lines. 
Sweave() doesn't recognize it, so it's completely ignored.

I don't think this is new behaviour; it's a consequence of the way 
Sweave looks for \SweaveOpts via regular expression.

Not quite sure what's going on in the second one yet...
