Comment:
According to [http://sourceforge.net/p/maxima/bugs/2501/ the upstream
report], that problem is also fixed
[http://maxima.git.sourceforge.net/git/gitweb.cgi?p=maxima/maxima;a=blobdiff;f=src/compar.lisp;h=15761dc5a29a6234f50181200821b84e28df40a4;hp=e9b2ec39d06886744a13901a65925d61dae18191;hb=1780660150446a1efe4ad149f0d23da6fdddd21f;hpb=8ad7e4288e11a9b1bbac31c811f91bf69f76b42f
here] and there is also a commit of the integral in question as a test.
{{{
expand(integrate(log(cot(x)-1),x,0,%pi/4));
-%i*li[2](%i+1)/2+%i*li[2](%i/2+1/2)/2-%i*li[2](1/2-%i/2)/2+%i*li[2](1-%i)/2-%pi*log(2)/4$
}}}
So I guess when the next Maxima after 5.29.1 is ready and we put it in, we
can try to close this report with a doctest.
