Subject: Error in fib.rb for 1.9

1.9 compiles and runs great on PCLinuxOS on my Toshiba Satelite
laptop: P4 1Gb

On cursory benchmarks, 1.9 is 2 ~ 8 times faster than 1.8.6 p111 on
some simple tests.

In the process I noticed the 1.9 fib.rb file in the /benchmarks/other-
lang directory is incorrect,
though fib.rb is correct under the /samples directory in 1.8.6 p111

fib.rb  -- 1.9.0  incorrect fib(0)=1, should be fib(0)=0
def fib n
  if n < 3
    1
  else
    fib(n-1) + fib(n-2)
  end
end

fib.rb -- 1.8.6 p111 correct for fib(0...n)
def fib n
  if n < 2
    n
  else
    fib(n-1) + fib(n-2)
  end
end

I see this error time and time again, though I continue to try to
stamp it out.
If the routine claims to produce the fibonacci numbers, produce ALL
the correct ones.
