New issue 3802 by [email protected]: factor(sqrt(1-x**2)) with x real is broken
http://code.google.com/p/sympy/issues/detail?id=3802

something at 34696f76efdc449ce1cb904781f3983c0a000728 broke this

formerly

factor(sqrt(1-x**2))
sqrt(-(x - 1)*(x + 1))

now

factor(sqrt(1-x**2))
I*sqrt(-x - 1)*sqrt(-x + 1)

Hopefully the code consolidation spoken of there will make this easy to track down.
