[WWcvs] pg: Make numbers be considered coefficients of x^0 in singlePowers mode, not just LimitedPolynomial-Strict context.

[dpvc v. a. <we...@ma...>]

Log Message:
-----------
Make numbers be considered coefficients of x^0 in singlePowers mode,
not just LimitedPolynomial-Strict context.  For LimitedPolynomials
with singlePowers set to 1, you can still do addition in the
constant term by using parentheses, e.g. 4x^2 + (3+4).
