#5046: directing tuples to ostream does not work as expected

     Type:  Bugs                     |      Status:  new    
Milestone:  To Be Determined         |   Component:  tuple  
  Version:  Boost 1.45.0             |    Severity:  Problem
 Keywords:  tuple output formatting  |  
-------------------------------------+--------------------------------------
 Assuming 'out' is a std::ostream the following code produces wrong
 output:


 {{{
 out <<  boost::tuples::set_open('[')
     <<  boost::tuples::set_close(']')
     <<  boost::tuples::set_delimiter(',')
     <<  std::setw(21) << std::right << some_boost_tuple;
 }}}


 Instead of being within a field of 21 spaces, the tuple is appended to
 those spaces.

 When fixing the bug - is it possible to also account for double precision
 settings by '<< std::std::setprecision(integer)'? That would be really
 helpful if dealing with tuples containing doubles.

 TIA
