+ * Use: Reads options. The routine should be more-or-less compatible

+ * features even than the standard GNU implementation.
+ *
+ * The precise manner of options parsing is determined by
+ * various flag settings, which are described below. By setting
+ * flag values appropriately, you can achieve behaviour very
+ * similar to most other getopt routines.
+ *
+ *
+ * How options parsing appears to users
+ *
+ * A command line consists of a number of `words' (which may
+ * contain spaces, according to various shell quoting
+ * conventions). A word may be an option, an argument to an
+ * option, or a non-option. An option begins with a special
+ * character, usually `%|-|%', although `%|+|%' is also used
+ * sometimes. As special exceptions, the word containing only a
+ * `%|-|%' is considered to be a non-option, since it usually
+ * represents standard input or output as a filename, and the
+ * word containing a double-dash `%|--|%' is used to mark all
+ * following words as being non-options regardless of their
+ * initial character.
+ *
+ * Traditionally, all words after the first non-option have been
+ * considered to be non-options automatically, so that options
+ * must be specified before filenames. However, this
+ * implementation can extract all the options from the command
+ * line regardless of their position. This can usually be
+ * disabled by setting one of the environment variables
+ * `%|POSIXLY_CORRECT|%' or `%|_POSIX_OPTION_ORDER|%'.
+ *
+ * There are two different styles of options: `short' and
+ * `long'.
+ *
+ * Short options are the sort which Unix has known for ages: an
+ * option is a single letter, preceded by a `%|-|%'. Short
+ * options can be joined together to save space (and possibly to
+ * make silly words): e.g., instead of giving options
+ * `%|-x -y|%', a user could write `%|-xy|%'. Some short
+ * options can have arguments, which appear after the option
+ * letter, either immediately following, or in the next `word'
+ * (so an option with an argument could be written as
+ * `%|-o foo|%' or as `%|-ofoo|%'). Note that options with
+ * optional arguments must be written in the second style.
+ *
+ * When a short option controls a flag setting, it is sometimes
+ * possible to explicitly turn the flag off, as well as turning
+ * it on, (usually to override default options). This is
+ * usually done by using a `%|+|%' instead of a `%|-|%' to
+ * introduce the option.
+ *
+ * Long options, as popularized by the GNU utilities, are given
+ * long-ish memorable names, preceded by a double-dash `%|--|%'.
+ * Since their names are more than a single character, long
+ * options can't be combined in the same way as short options.
+ * Arguments to long options may be given either in the same
+ * `word', separated from the option name by an equals sign, or
+ * in the following `word'.
+ *
+ * Long option names can be abbreviated if necessary, as long
+ * as the abbreviation is unique. This means that options can
+ * have sensible and memorable names but still not require much
+ * typing from an experienced user.
+ *
+ * Like short options, long options can control flag settings.
+ * The options to manipulate these settings come in pairs: an
+ * option of the form `%|--set-flag|%' might set the flag, while
+ * an option of the form `%|--no-set-flag|%' might clear it.
+ *
+ * It is usual for applications to provide both short and long
+ * options with identical behaviour. Some applications with
+ * lots of options may only provide long options (although they
+ * will often be only two or three characters long). In this
+ * case, long options can be preceded with a single `%|-|%'
+ * character, and negated by a `%|+|%' character.
+ *
+ * Finally, some (older) programs accept arguments of the form
+ * `%%@.{"-"<number>}%%', to set some numerical parameter,
+ * typically a line count of some kind.
+ *
+ *
+ * How programs parse options
+ *
+ * An application parses its options by calling mdwopt
+ * repeatedly. Each time it is called, mdwopt returns a value
+ * describing the option just read, and stores information about
+ * the option in a data block. The value %$-1$% is returned
+ * when there are no more options to be read. The `%|?|%'
+ * character is returned when an error is encountered.
+ *
+ * Before starting to parse options, the value @data->ind@ must
+ * be set to 0 or 1. The value of @data->err@ can also be set,
+ * to choose whether errors are reported by mdwopt.
+ *
+ * The program's `@argc@' and `@argv@' arguments are passed to
+ * the options parser, so that it can read the command line. A
+ * flags word is also passed, allowing the program fine control
+ * over parsing. The flags are described above.
+ *
+ * Short options are described by a string, which once upon a
+ * time just contained the permitted option characters. Now the
+ * options string begins with a collection of flag characters,
+ * and various flag characters can be put after options
+ * characters to change their properties.
+ *
+ * If the first character of the short options string is
+ * `%|+|%', `%|-|%' or `%|!|%', the order in which options are
+ * read is modified, as follows:
+ *
+ * `%|+|%' forces the POSIX order to be used. As soon as a non-
+ * option is found, mdwopt returns %$-1$%.
+ *
+ * `%|-|%' makes mdwopt treat non-options as being `special'
+ * sorts of option. When a non-option word is found, the
+ * value 0 is returned, and the actual text of the word
+ * is stored as being the option's argument.
+ *
+ * `%|!|%' forces the default order to be used. The entire
+ * command line is scanned for options, which are
+ * returned in order. However, during this process,
+ * the options are moved in the @argv@ array, so that
+ * they appear before the non- options.
+ *
+ * A `%|:|%' character may be placed after the ordering flag (or
+ * at the very beginning if no ordering flag is given) which
+ * indicates that the character `%|:|%', rather than `%|?|%',
+ * should be returned if a missing argument error is detected.
+ *
+ * Each option in the string can be followed by a `%|+|%' sign,
+ * indicating that it can be negated, a `%|:|%' sign indicating
+ * that it requires an argument, or a `%|::|%' string,
+ * indicating an optional argument. Both `%|+|%' and `%|:|%' or
+ * `%|::|%' may be given, although the `%|+|%' must come first.
+ *
+ * If an option is found, the option character is returned to
+ * the caller. A pointer to an argument is stored in
+ * @data->arg@, or @NULL@ is stored if there was no argument.
+ * If a negated option was found, the option character is
+ * returned ORred with @OPTF_NEGATED@ (bit 8 set).
+ *
+ * Long options are described in a table. Each entry in the
+ * table is of type @struct option@, and the table is terminated
+ * by an entry whose @name@ field is null. Each option has
+ * a flags word which, due to historical reasons, is called
+ * @has_arg@. This describes various properties of the option,
+ * such as what sort of argument it takes, and whether it can
+ * be negated.
+ *
+ * When mdwopt finds a long option, it looks the name up in the
+ * table. The index of the matching entry is stored in the
+ * @longind@ variable, passed to mdwopt (unless @longind@ is 0):
+ * a value of %$-1$% indicates that no long option was
+ * found. The behaviour is then dependent on the values in the
+ * table entry. If @flag@ is nonzero, it points to an integer
+ * to be modified by mdwopt. Usually the value in the @val@
+ * field is simply stored in the @flag@ variable. If the flag
+ * @OPTF_SWITCH@ is set, however, the value is combined with
+ * the existing value of the flags using a bitwise OR. If
+ * @OPTF_NEGATE@ is set, then the flag bit will be cleared if a
+ * matching negated long option is found. The value 0 is
+ * returned.
+ *
+ * If @flag@ is zero, the value in @val@ is returned by mdwopt,
+ * possibly with bit 8 set if the option was negated.
+ *
+ * Arguments for long options are stored in @data->arg@, as
+ * before.
+ *
+ * Numeric options, if enabled, cause the value `%|#|%' to be
+ * returned, and the numeric value to be stored in @data->opt@.
+ *
+ * If the flag @OPTF_ENVVAR@ is set on entry, options will be
+ * extracted from an environment variable whose name is built by
+ * capitalizing all the letters of the program's name. (This
+ * allows a user to have different default settings for a
+ * program, by calling it through different symbolic links.)
