.rjust dosn't seem to be working correctly, no error, but it's not
right justifying either.

my output for the .rjust looks like this:
Chapter 1                     Getting Started
             page 1
Chapter 2                     Numbers
             page 9
Chapter 3                     Letter
            page 13

here is the first line (Chapter 1...)

puts(              toc[1].ljust(line_width) + toc[2].ljust(line_width)
+ toc[3].rjust(line_width))

I hand tweaked teh .rjust parameter with hard numbers .rjust(20)

        .rjust(25), etc and that helped but I thought .rjust would
make sure the last letters of the strings would all line up.
