 program_options::collect_unrecognized does not properly collect
 unregistered options parsed via parse_config_file when parse_config_file
 is set to accept unregistered options.

 Test case attached as test.cpp.

 Compare the number of options that have unregistered == true vs the number
 of elements in recognized.  I expect that the number of unregistered
 options is identical to the number of unrecognized options collected based
 upon
 [http://www.boost.org/doc/libs/1_40_0/doc/html/boost/program_options/collect_unrecognized.html

 the documentation].

 It looks like parse_config_file fails to set
 basic_option<charT>.original_tokens correctly, and collect_unrecognized
 seems to rely on the original_tokens to do its job.  The trouble involves
 boost/program_options/detail/parsers.hpp:135 where the std::copy call is a
 NOP but should not be.
