std bit not set properly

Is is possible to set the "std" bit to the ideal I when I do I = std(f,g); ? For example:

The following code gives a warning _ is no standard basis I = std(f,g); reduce(x,I);

Whereas the following code, which means the same thing, does not give the warning: I = f,g; I = std(I); reduce(x,I);

std(f,g) for f and g being polynomials can be:


The first case is probably meant, and works without warning, the second requires ideal(f) to be a standard basis, which results in a warning (and it should, as this is probably not true in rings with zero-divisors)
