New description:

 The patch at #13014 caused an unacceptable slow-down for
 {{{
 sage: time p = polar_plot(lambda t:
 (100/(100+(t-pi/2)^8))*(2-sin(7*t)-cos(30*t)/2), -pi/4, 3*pi/2,
 color="red",plot_points=1000)
 }}}

 The attached patch reverts part of #13014.  Interestingly, no doctests
 need to be changed!
