Comment (by kcrisman):
Perhaps more importantly, sometimes the principal value returned is
correct even without considering improper integrals!
{{{
(%i1) integral(sec(x), x, -%pi/4, %pi/4);
%pi %pi
(%o1) integral(sec(x), x, - ---, ---)
4 4
(%i2) integrate(sec(x), x, -%pi/4, %pi/4);
Principal Value
sqrt(2) + 2 sqrt(2) - 2
(%o2) log(-----------) - log(- -----------)
2 2
}}}
See #17608.
