Well, && will help some.

I think the algorothm is wrong in this case. I would go for

template< class SinglePassRange, class WritableForwardRange >
void overwrite( const SinglePassRange&, WriteForwardRange& );

template< class SinglePassRange, class WritableForwardRange >
void overwrite( const SinglePassRange&, const WriteForwardRange& );

(which in C++0x can become one function using &&).
