Arg(fourier_cn(...)) returns different answers
Suppose f(x):=when(x>-Pi and x<0,-1,when(x>=0 and x<Pi,1,0)).

Then Arg(fourier_cn(f(x),x,2*Pi,n,-Pi)) returns different answers accordingly to the assumption for n. With integer assumpton for n Arg(fourier_cn(...)) returns a correct answer, but without any assumption for n it returns the result which is like odd and even indexes swaped while substituting various integer values n.

Is it proper?
