Add a note about pow(x,y) equalling x**y (the "**" operator
was used unmotivated in the pow() docs)

\begin{funcdesc}{pow}{x, y\optional{, z}}
Return \var{x} to the power \var{y}; if \var{z} is present, return
\var{x} to the power \var{y}, modulo \var{z} (computed more
- efficiently than \code{pow(\var{x}, \var{y}) \%\ \var{z}}). The
- arguments must have numeric types. With mixed operand types, the

+ The two-argument form \code{pow(\var{x}, \var{y})} is equivalent to using
+ the power operator: \code{\var{x}**\var{y}}.

+ The arguments must have numeric types. With mixed operand types, the
coercion rules for binary arithmetic operators apply. For int and
long int operands, the result has the same type as the operands
(after coercion) unless the second argument is negative; in that
