mount fixes

[Alfred M. Szmidt]

Fixes a old bug that makes mount work with the common arguments.

It hasn't been tested heavily, but the simple stuff works.

It also has a small syntatic change that is self explanatory.

        * mount.c (argp_opts): Enabled never-enabled options and added
        long versions: --verbose/-v, --remount/--update/-u,
        --writable/-w, --readonly/-r and --options/-o.  Reported by
        Ben Asselstine.

        * mount (parse_opt) <u>: Use "update" instead of the deprecated
        "remount" argument.
