Clearly this is a bug.

Subject: An integration question
I don't understand how/why Maxima returns the following:
(%i3)
integrate(cos(x)-cos(x-c),x,0,c/2)=%pi-c-integrate(cos(x-c),x,c,%pi/2+c);
Is c positive, negative, or zero?
pos;
(%o3) 2*sin(c/2)-sin(c) = -c+sin((4*%pi*false-%pi)/2)-sin(2*%pi*false)+%pi
What is this "false" doing in the answer? In case it plays any role,
here is the build_info:
