Debounce example doesn't work as described.

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Compile and run Examples > Digital > Debounce example included with the IDE.

What is the expected output? What do you see instead?

According to the documentation at the start of the code and on the website the 
LED should be toggled with each button press.  Instead the LED just matches the 
button state.

What version of the Arduino software are you using? On what operating
system?  Which Arduino board are you using?

0018
MacOS X 10.6.4
Duemilanove

Please provide any additional information below.

I'm attaching a modified version which does what the program is described to 
do.  Feel free to use it as you please.  It may need to be modified to be more 
readable for beginner programmers...

Scott,

I've looked at the example, but I don't understand one thing: if we want to 
keep the example as is, why we are using debouncing? with the actual behaviour 
it would be simpler to do

digitalWrite(ledPin, digitalRead(buttonPin));
