integrate(atan(x*(x^2+1)^(1/2)),x)
integrate(tanh(x)/(exp(x)+exp(2*x))^(1/2),x)
integrate((2+2*tan(x)+tan(x)^2)^(1/2),x)
...
These integrals are different between trunk and this patch.
(same as 1.3.9.)

Just to clarify, you revert some class of biquadratic to old behavior,
right?
'quartic2' only handles case of complex roots, if is did anything to
equations with reals roots, then this was a bug. In the patch added
case for biquadratic should handle all cases that where correctly
handled by version in trunk and handle also cases with real roots.
The only unhandled biquadratics are ones where we can not determine
configuration of roots. I think that version in trunk is unable
to handle them too.
