<blink>  Learn something new every frickin' day.  I was not familiar with
this extra cute magic behavior of "print ," at the end of a line.  I
guess I like it, but I'm still a bit suspicious for no reason -- I think
I got confused way back when I was first learning Python and got the
double-spaced output of regular print, assuming that a space still got
stuck at the end of a line with "print ,", and never actually trying it.

Let this be a lesson to you newbies.  ;-)  (But I have no clue what
lesson it should be...)
