std.getopt.GetOptException@/home/nils/d/dmd/dmd2/linux/bin64/../../src/phobos/std/getopt.d(597):
Unrecognized option --help

The documentation doesn't say that the implicit help option only works with
config.passThrough. The examples that use helpWanted don't use
config.passThrough.

Pull request is on the way.
