On the other hand, if you want to have a different behavior, then in the ideal
case this should work:
Index: lang.opt

Unfortunately, the handlers for the options are set up such that the language
specific handlers are executed before the common_handler (which is executed
before the target-specific handler).
Joseph, why is that so? I think it makes sense that the FEs can override the
common settings, like the targets can.
The alternative is to duplicate the option in every FE and remove it from
common.opt. That seems quite ugly to me.
