I would like to be able to get plots that do not have artifacts from discontinuities without having to know where the problem[s] will be in advance. For example, I would like to be able to say Plot[1/(1+x), {x,-2,1}] and get a graph without the vertical line at x==-1. Though p1=Plot[1/(1+x), {x,-2,-1}, DisplayFunction->Identity]; p2=Plot[1/(1+x), {x,-1,1}, DisplayFunction->Identity]; Show[p1,p2, DisplayFunction->$DisplayFunction]; does the trick, it requires my anticipation of the problem at x==1.
