you mean that the options in the { } refer to the previous specified 
--animal, is that right?

Do you mean that { } in command line are standard for getopt?  Sorry 
about my ignorance but I really didn't know about it.  Could you please 
provide me with some link to this feature?

you get an error, don't you?

I'm not sure I understood this point: it is already possible to specify 
a flag option with an option on/off argument...

I'm a little skeptical about this: if one defines the .ggo file with the 
same name of the program, the default behaviour as you request would 
then to, silently, override the main file...  I feel safer with the 
default cmdline.c and cmdline.h :-)
