/*

 * `type`::

 *   holds the type of the option, you must have an OPTION_END last in your

 *   array.

 *

 * `short_name`::

 *   the character to use as a short option name, '\0' if none.

 *

 * `long_name`::

 *   the long option (without the leading dashes) or subcommand name,

 *   NULL if none.

 *

 * `value`::

 *   stores pointers to the values to be filled.

 *

 * `precision`::

 *   precision of the integer pointed to by `value` in number of bytes. Should

 *   typically be its `sizeof()`.

 *

 * `argh`::

 *   token to explain the kind of argument this option wants. Does not

 *   begin in capital letter, and does not end with a full stop.

 *   Should be wrapped by N_() for translation.

 *   Is automatically enclosed in brackets when printed, unless it

 *   contains any of the following characters: ()<>[]|

 *   E.g. "name" is shown as "<name>" to indicate that a name value

 *   needs to be supplied, not the literal string "name", but

 *   "<start>,<end>" and "(this|that)" are printed verbatim.

 *

 * `help`::

 *   the short help associated to what the option does.

 *   Must never be NULL (except for OPTION_END and OPTION_SUBCOMMAND).

 *   OPTION_GROUP uses this pointer to store the group header.

 *   Should be wrapped by N_() for translation.

 *

 * `flags`::

 *   mask of parse_opt_option_flags.

 *   PARSE_OPT_OPTARG: says that the argument is optional (not for BOOLEANs)

 *   PARSE_OPT_NOARG: says that this option does not take an argument

 *   PARSE_OPT_NONEG: says that this option cannot be negated

 *                   (i.e. rejects "--no-<option>")

 *   PARSE_OPT_HIDDEN: this option is skipped in the default usage, and

 *                     shown only in the full usage.

 *   PARSE_OPT_LASTARG_DEFAULT: says that this option will take the default

 *        value if no argument is given when the option

 *        is last on the command line. If the option is

 *        not last it will require an argument.

 *        Should not be used with PARSE_OPT_OPTARG.

 *   PARSE_OPT_NODASH: this option doesn't start with a dash; can only be a

 *           short option and can't accept arguments.

 *   PARSE_OPT_LITERAL_ARGHELP: says that argh shouldn't be enclosed in brackets

 *        (i.e. '<argh>') in the help message.

 *        Useful for options with multiple parameters.

 *   PARSE_OPT_NOCOMPLETE: by default all visible options are completable

 *         by git-completion.bash. This option suppresses that.

 *   PARSE_OPT_COMP_ARG: this option forces to git-completion.bash to

 *       complete an option as --name= not --name even if

 *       the option takes optional argument.

 *

 * `callback`::

 *   pointer to the callback to use for OPTION_CALLBACK

 *

 * `defval`::

 *   default value to fill (*->value) with for PARSE_OPT_OPTARG.

 *   OPTION_{BIT,SET_INT} store the {mask,integer} to put in the value when met.

 *   CALLBACKS can use it like they want.

 *

 * `ll_callback`::

 *   pointer to the callback to use for OPTION_LOWLEVEL_CALLBACK

 *

 * `subcommand_fn`::

 *   pointer to a function to use for OPTION_SUBCOMMAND.

 *   It will be put in value when the subcommand is given on the command line.
