Nice. The man page for 'getopt_long' is unclear whether setting POSIXLY_CORRECT in the environment would break this (that is, setting POSIXLY_CORRECT has the same effect as a leading '+'; but you can't have both leading '+' and leading '-' and when both are set, it is not clear which one wins). But that's a corner case that I don't think will ever bite us in real life.
