#1590: shared_ptr documentation inconsistency

     Type:  Bugs                     |      Status:  new      
Milestone:  Boost 1.36.0             |   Component:  smart_ptr
  Version:  Boost Development Trunk  |    Severity:  Problem  
 Keywords:                           |  
-------------------------------------+--------------------------------------
 The default shared_ptr constructor, which creates an empty shared_ptr,
 gives "use_count() == 0" as a post condition.  However, the documentation
 for
 use_count says it returns "an unspecified nonnegative value when *this is
 empty".  I'd like it to return 0 for an empty shared_ptr, as that appears
 to
 be the only way to distinguish an empty shared_ptr from one sharing
 ownership
 of a null pointer.
