 Plot should not allow this to go without an error:
 {{{
 Q = plot(df(Deltax=.01),(x,-pi,3*pi),color='red',linestyle='..'); Q
 }}}
 What the user likely meant (well, since it was me, definitely meant) was:
 {{{
 Q = plot(df(Deltax=.01),(x,-pi,3*pi),color='red',linestyle='..'); Q
 }}}
 But there is no error thrown.  Scrolling all the way down `plot?` each
 time is tedious.

 (We should probably also look at all plot options and make sure we get
 errors if we give bad input.  That would be a big project, esp. since mpl
 likely will change available input.)
