   Your welcome.  I just saw another minor documentation bug.  In the 
documentation for use_count() it says it returns an unspecified nonnegative 
value when *this is empty.  This should be changed to say it returns 0 when 
*this is empty.  Also,  the documentation on "unique()" says  "If you are 
using unique() to implement copy on write, do not rely on a specific value 
when the stored pointer is zero".  Does this still apply?
