tiny correction to manual: '^' token

[Richard Tucker <rtucker@...>]

In the Lua 4.0 reference manual at
http://www.tecgraf.puc-rio.br/lua/manual/manual.html
section 4.1 (Lexical Conventions) says:

>The following strings denote other tokens: 
> ~=    <=    >=    <     >     ==    =     +     -     *     /     
> (     )     {     }     [     ]     ;     ,     .     ..    ...

Shouldn't the token ^ (for exponentiation) be added to this list?
(This actually led me to forget that lua had an exponentiation
operator for a while.)
