[boost] Wave/flex_string and replace< InputIterator > bug

Hi all,

I am implementing test cases to validate the implementation of my 
fixed_string class and basic_string_impl (based on flex_string) and noticed 
a defect in the implementation of:

   template< typename InputIterator >
   inline string_type & replace( iterator i1, iterator i2, InputIterator j1, 
InputIterator j2 );

It handles the Integral case fine, but when the InputIterators are actually 
iterators, it asserts false, where the standard dictates it returns:

   replace( i1, i2, basic_string( j1, j2 ));

or equivalent behaviour, e.g. in the implementation I'm using:

   replace( i1, i2, std::distance( j1, j2 ), char_type());
   std::copy( j1, j2, i1 );

Is there any specific reason for this, or is it an implementation bug?

Regards,
Reece
