hm, it shouldn't really "break" anything, it would just make it possible to 
change it's behavior.

maybe i didn't make myself clear enough: i don't propose to put that formals() 
call into the default configuration. i just meant that if we fixed the 
override function to respect the setting of 'save', the above line would be 
*possible*. you can put it in the options already, but it will have no effect 
at the moment, because RKWard silently ignores all arguments to q().

yes, that would still remain the default. so unless you actively change the 
configuration, RKWard's default behavior wouldn't change at all. but *if* you 
would like RKWard to close differently, you could do that then.

correct. so an open question would be where to save the default workspace in 
case you've set it to 'save="yes"'. it could for instance be a file in

  ~/.local/share/rkward/

because the current working directory doesn't make much sense, as you usually 
don't start RKWard from a particular/changing working directory. an 
alternative could be RKWard's defined startup working directory.

RKWard overrides some (very few) R core functions. in this case it's likely 
because it depends on a running R session in the backend, so a user shouldn't 
be able so simply call q() and crash the application ;-)
