Comment:
Okay, correctly checks #8582 and does the right stuff from #8624 that we
need. I agree with Minh that the other stuff was not needed.
Very odd about the `sqrt(x+sqrt(x))` thing. I think that Burcin is right;
we never enabled the abs integrate - Maxima just got better at the #8624
integrals on its own:
{{{

The function bug_report() provides bug reporting information.
(%i1) integrate(abs(cos(x))*sin(x),x,%pi/2,%pi);
1
(%o1) -
2
}}}
So I respectfully request that someone with the authority reopen that
ticket as he suggests, with new title. Using `abs_integrate` does solve
the square root integral in question (`sqrt(x+sqrt(x))`).
However, I think that this one can still be merged, since there are no
problems with these, and they were verified as correct on the relevant
tickets, and it passes the tests, of course, and applies, of course.
To release manager/patchbot: doc fix only, apply trac-10434_doctests.patch
