Comment #13 on issue 829 by smi...@gmail.com: Improve simplify() to handle result from integrate(log(k**2-m**2), k)
http://code.google.com/p/sympy/issues/detail?id=829

var('k m')
(k, m)
(integrate(log(k**2-m**2), k) )
k*log(k**2 - m**2) - 2*k - 2*m*(log(k - m)/2 - log(k + m)/2)
simplify(_)
k*log(k**2 - m**2) - 2*k - m*(log(k - m) - log(k + m))

This is the same as comment #5's result, but factored wrt m. So only a test needs to be added.
