Hmm, no - an error message produced by this code doesn't look neat,
nor informative:
Incorrect value for option 'log, log_format or log_nonblock': Illegal parametrs log, log_nonblock
I guess, I see now why all these checks sit in box.cc instead of being
isolated in say.c - for the sake of error reporting. Sorry I confused
you :-( If you don't have a better idea in mind, let's return to where
we started, i.e. to removal of say_check_init_str(). Since it's not
going to be used after you remove the call to it from box_check_say(),
please remove it from say.[hc] as well.
