OK, good.

In SAGE-1.5, the default polynomial ring naming is exactly as in SAGE-1.4.
I fully implemented the automatic injection of polynomial ring variables
when the rings are created, but it is *off* by default.   When it is on,
it is verbose, and lets the user know what is happening.

OK.   Thanks.
