Can I just run the plan by you then? Actually looks even a little 
simpler than I was thinking. The docs don't discuss the style options 
really. Filenames are relative to the program_options directories:

   - cmdline.hpp

     Add a new value to 'enum style_t'. (I'll use 'allow_interspersed'
     if there's no objection)

   - src/cmdline.cpp and details/cmdline.hpp

     Take my patch from before and change "false /* or true for the
     behavior I want */" to "m_style & allow_interspersed"

Then how do I use it? Do something like

  command_line_parser(argc, argv)
      .style(default_style | allow_interspersed)
      .run()
?
