Constants? "true"/"false"

I wonder if at....

http://www.arduino.cc/en/Reference/HomePage

... in the section "Constants", whether...

true

... and ...

false

... should be added? If an expert knows that they certainly should, I hope they'll do that? (Add them).

From the way the Arduino development software syntax highlighting recognized the words, it would seem that they are keywords, and worthy of inclusion in the official guide.

But maybe I'm missing something.

The more I think about this, the more I think they ought to be in the constants list, so I will make the edit in a few days....

UNLESS AN EXPERT TELLS ME I'M WRONG..... Please? !

I would love to see them added too.

Added.
