I am a bit confused by this patch.  You do call the hook after C-c C-c  
has done its thing.  Which is OK, but this is not what the  
documentation in your hook variable says.  That documentation seems to  
have been copied from the normal ctrl-c-ctrl-c hook, and these hooks  
are used in a different way:  They establish *alternative*  
functionality to the normal C-c C-c actions.  So if any of the hook  
functions returns a non-nil value, the normal C-c C-c functionality  
will *not* be executed.

So what are your true intentions, and can you make code and  
documentation macht up?

Thanks
