Comment (by Leo Goodstadt <boost@…>):

 I would like to add my support to this feature, having long patched my
 version of program_options to support this.

 The text of "arg" is called "metavar" in the python optparse module, and
 opt_name in GNU genparse.
 I am very used to "metavar" from python but it is very obscure for non-
 python users.

 "arg" is either the name of the argument/value for the option, or a
 placeholder for the argument/value for the option. In use, it is commonly
 the *type* of the argument.

 So we have four choices:
 1) metavar (from python)
 2) argument_name | arg_name | option_value_name | value_name
 3) argument_placeholder_name | arg_placeholder | value_placeholder
 4) argument_type | arg_type

 My preference is for something from (2).
