Hello,

in simplifying an expression, I came accross this:

(%i2) is(1/(1-x) = -1/(x-1));
(%o2)                                false
(%i3) radcan(1/(1-x));  
                                        1
(%o3)                               - -----
                                      x - 1

I would expect is(1/(1-x) = -1/(x-1)) to evaluate to true. Am I
missing something obvious here?
