-   expect this.

-   as if it were the argument of an option with character code 1.
-   Using `-' as the first character of the list of option characters
-   selects this mode of operation.
-
-   The special argument `--' forces an end of option-scanning regardless

-
-   If an element of ARGV starts with '-', and is not exactly "-" or "--",
-   then it is an option element.  The characters of this element
-   (aside from the initial '-') are option characters.  If `getopt'
-   is called repeatedly, it returns successively each of the option characters
-   from each of the option elements.
-
-   If `getopt' finds another option character, it returns that character,
-   updating `optind' and `nextchar' so that the next call to `getopt' can
-   resume the scan with the following option character or ARGV-element.
-
-   If there are no more option characters, `getopt' returns -1.
-   Then `optind' is the index in ARGV of the first ARGV-element
-   that is not an option.  (The ARGV-elements have been permuted
-   so that those that are not options now come last.)
-
-   OPTSTRING is a string containing the legitimate option characters.
-   If an option character is seen that is not listed in OPTSTRING,
-   return '?' after printing an error message.  If you set `opterr' to
-   zero, the error message is suppressed but we still return '?'.
-
-   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
-   so the following text in the same ARGV-element, or the text of the following
-   ARGV-element, is returned in `optarg'.  Two colons mean an option that
-   wants an optional arg; if there is text in the current ARGV-element,
-   it is returned in `optarg', otherwise `optarg' is set to zero.
-
-   If OPTSTRING starts with `-' or `+', it requests different methods of
-   handling the non-option ARGV-elements.
-   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
-
-   Long-named options begin with `--' instead of `-'.
-   Their names may be abbreviated as long as the abbreviation is unique
-   or is an exact match for some defined option.  If they have an
-   argument, it follows the option name in the same ARGV-element, separated
-   from the option name by a `=', or else the in next ARGV-element.
-   When `getopt' finds a long-named option, it returns 0 if that option's
-   `flag' field is nonzero, the value of the option's `val' field
-   if the `flag' field is zero.
-
-   The elements of ARGV aren't really const, because we permute them.
-   But we pretend they're const in the prototype to be compatible
-   with other systems.
-
-   LONGOPTS is a vector of `struct option' terminated by an
-   element containing a name which is zero.
-
-   LONGIND returns the index in LONGOPT of the long-named option found.
-   It is only valid when a long-named option has been found by the most
-   recent call.
-
-   If LONG_ONLY is nonzero, '-' as well as '--' can introduce

+/* Scan elements of ARGV (whose length is ARGC) for option characters
+   given in OPTSTRING.
+
+   If an element of ARGV starts with '-', and is not exactly "-" or "--",
+   then it is an option element.  The characters of this element
+   (aside from the initial '-') are option characters.  If `getopt'
+   is called repeatedly, it returns successively each of the option characters
+   from each of the option elements.
+
+   If `getopt' finds another option character, it returns that character,
+   updating `optind' and `nextchar' so that the next call to `getopt' can
+   resume the scan with the following option character or ARGV-element.
+
+   If there are no more option characters, `getopt' returns -1.
+   Then `optind' is the index in ARGV of the first ARGV-element
+   that is not an option.  (The ARGV-elements have been permuted
+   so that those that are not options now come last.)
+
+   OPTSTRING is a string containing the legitimate option characters.
+   If an option character is seen that is not listed in OPTSTRING,
+   return '?' after printing an error message.  If you set `opterr' to
+   zero, the error message is suppressed but we still return '?'.
+
+   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+   so the following text in the same ARGV-element, or the text of the following
+   ARGV-element, is returned in `optarg'.  Two colons mean an option that
+   wants an optional arg; if there is text in the current ARGV-element,
+   it is returned in `optarg', otherwise `optarg' is set to zero.
+
+   If OPTSTRING starts with `-' or `+', it requests different methods of
+   handling the non-option ARGV-elements.
+   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+   Long-named options begin with `--' instead of `-'.
+   Their names may be abbreviated as long as the abbreviation is unique
+   or is an exact match for some defined option.  If they have an
+   argument, it follows the option name in the same ARGV-element, separated
+   from the option name by a `=', or else the in next ARGV-element.
+   When `getopt' finds a long-named option, it returns 0 if that option's
+   `flag' field is nonzero, the value of the option's `val' field
+   if the `flag' field is zero.
+
+   The elements of ARGV aren't really const, because we permute them.
+   But we pretend they're const in the prototype to be compatible
+   with other systems.
+
+   LONGOPTS is a vector of `struct option' terminated by an
+   element containing a name which is zero.
+
+   LONGIND returns the index in LONGOPT of the long-named option found.
+   It is only valid when a long-named option has been found by the most
+   recent call.
+
+   If LONG_ONLY is nonzero, '-' as well as '--' can introduce
+   long-named options.  */
