545,Program_options: Fails to parse options with a common root,rleigh,Vladimir Prus,"{{{
Given the following testcase:

#include <iostream>
#include <boost/program_options.hpp>
namespace opt = boost::program_options;

int main(int   argc,
	 char *argv[])
{
  try
    {
      bool all, all_chroots, all_sessions;

      opt::options_description chroot(""Chroot selection"");
      chroot.add_options()
	(""all,a"", ""Select all chroots and active sessions"")
	(""all-chroots"", ""Select all chroots"")
	(""all-sessions"", ""Select all active sessions"");

      opt::variables_map vm;
      opt::store(opt::parse_command_line(argc, argv,
chroot), vm);
      opt::notify(vm);

      if (vm.count(""all""))
	all = true;
      if (vm.count(""all-chroots""))
	all_chroots = true;
      if (vm.count(""all-sessions""))
	all_sessions = true;

      return 0;
    }
  catch (std::exception const& e)
    {
      std::cerr << e.what() << std::endl;
      return 1;
    }
}

$ g++ -o opt opt.cc -lboost_program_options
$ ./opt --help
unknown option help
$ ./opt --all-chroots
$ ./opt --all-sessions
$ ./opt --all
ambiguous option all

--all is not abiguous, since it's an exact match.  It's
not ambigous for GNU getopt or GLib GOption, so this is
IMHO a bug.
