patch applied (cabal): Rejig --list-options handling so it takes priority

Tue Dec 18 11:16:36 PST 2007 Duncan Coutts * Rejig --list-options handling so it takes priority --list-options no takes priority over errors in other flags and over --help this is so that it can be used consistently for command completion without returning garbage (ie error messages on ill formed partial command lines or producing --help output). Also make --list-options list all the common options appart from itself, so that's just --help at the moment. M ./Distribution/Simple/Command.hs -6 +9
