4927	Incorrect behavior of  method clear() for class program_options::variables_map	degtyariov.a@…	Vladimir Prus	"The method clears only members inherited from the std::map. But what about other members of class variables_map (m_final, m_required)?

It is lead to strange behavior in next case:
 1) parse default config file and fill corresponding ""config file"" variables_map;

 2) parse command line (into another variables_map), get name of custom config file;

 3) call clear() for ""config file"" variables_map and parse new file and refill ""config file"" variables_map again;

 4) output all values of the ""config file"" variables_map and denote which of them are defaulted

Workaround: reassign new instance of variables_map instead call clear().
