New description:

 Maxima's `abs_integrate` contributed package gives us lots of nice new
 integrals, but also really breaks a lot of stuff, apparently.  Add to this
 list as you see fit:
 * #13733 (fixed but note unwanted interactions)
 * #11590 sgn() function (not reported upstream?)
 * #14591 cosh integral incorrect because of abs_integrate
 * #16643 integrate() infinite loop
 * #17183 another abs_integrate error
 * #17468 log(abs(sin())) problem
 ----

 Old:

 Can someone more knowledgeable about using maxima for integration
 determine what the right warning to show is and when to show it?  See
 #12691 for what a stopgap is.
