New issue 1530 by asmeurer: logcombine function for combining logarithms http://code.google.com/p/sympy/issues/detail?id=1530 I wrote this logcombine function a while ago for my work in dsolve, but I haven't finished the work in dsolve yet. But I figured that the logcombine function could be put in, as it is independent of dsolve. The function combines logarithms like log(x)+log(y) => log(x*y) and 2*log(x) => log(x**2). It defaults to only combining if the arguments have proper assumptions (the arguments must be positive and the exponents/coefficients must be real for these identities to be true). You can override these by choosing assume_pos_real = True. See the docstring for more info.
