  79  * `type`::
  80  *   holds the type of the option, you must have an OPTION_END last in your
  81  *   array.
  82  *
  83  * `short_name`::
  84  *   the character to use as a short option name, '\0' if none.
  85  *
  86  * `long_name`::
  87  *   the long option (without the leading dashes) or subcommand name,
  88  *   NULL if none.
  89  *
  90  * `value`::
  91  *   stores pointers to the values to be filled.
  92  *
  93  * `argh`::
  94  *   token to explain the kind of argument this option wants. Does not
  95  *   begin in capital letter, and does not end with a full stop.
  96  *   Should be wrapped by N_() for translation.
  97  *   Is automatically enclosed in brackets when printed, unless it
  98  *   contains any of the following characters: ()<>[]|
  99  *   E.g. "name" is shown as "<name>" to indicate that a name value
 100  *   needs to be supplied, not the literal string "name", but
 101  *   "<start>,<end>" and "(this|that)" are printed verbatim.
 102  *
 103  * `help`::
 104  *   the short help associated to what the option does.
 105  *   Must never be NULL (except for OPTION_END and OPTION_SUBCOMMAND).
 106  *   OPTION_GROUP uses this pointer to store the group header.
 107  *   Should be wrapped by N_() for translation.
 108  *
 109  * `flags`::
 110  *   mask of parse_opt_option_flags.
 111  *   PARSE_OPT_OPTARG: says that the argument is optional (not for BOOLEANs)
 112  *   PARSE_OPT_NOARG: says that this option does not take an argument
 113  *   PARSE_OPT_NONEG: says that this option cannot be negated
 114  *   PARSE_OPT_HIDDEN: this option is skipped in the default usage, and
 115  *                     shown only in the full usage.
 116  *   PARSE_OPT_LASTARG_DEFAULT: says that this option will take the default
 117  *                              value if no argument is given when the option
 118  *                              is last on the command line. If the option is
 119  *                              not last it will require an argument.
 120  *                              Should not be used with PARSE_OPT_OPTARG.
 121  *   PARSE_OPT_NODASH: this option doesn't start with a dash; can only be a
 122  *                     short option and can't accept arguments.
 123  *   PARSE_OPT_LITERAL_ARGHELP: says that argh shouldn't be enclosed in brackets
 124  *                              (i.e. '<argh>') in the help message.
 125  *                              Useful for options with multiple parameters.
 126  *   PARSE_OPT_NOCOMPLETE: by default all visible options are completable
 127  *                         by git-completion.bash. This option suppresses that.
 128  *   PARSE_OPT_COMP_ARG: this option forces to git-completion.bash to
 129  *                       complete an option as --name= not --name even if
 130  *                       the option takes optional argument.
 131  *
 132  * `callback`::
 133  *   pointer to the callback to use for OPTION_CALLBACK
 134  *
 135  * `defval`::
 136  *   default value to fill (*->value) with for PARSE_OPT_OPTARG.
 137  *   OPTION_{BIT,SET_INT} store the {mask,integer} to put in the value when met.
 138  *   CALLBACKS can use it like they want.
 139  *
 140  * `ll_callback`::
 141  *   pointer to the callback to use for OPTION_LOWLEVEL_CALLBACK
 142  *
 143  * `subcommand_fn`::
 144  *   pointer to a function to use for OPTION_SUBCOMMAND.
 145  *   It will be put in value when the subcommand is given on the command line.
