I liked your other suggestion of having %E or something provide 
errno() and strerror(). I agree with Marc's comments that we need 
both. That way we can still do this with one logging function. ???

As for filename, I don't think this is something that we want to 
see for every error, and I'm not to keen on the adjustable 
verbosity stuff either. How about another token to get that? 
Trapping signals to change verbosity would be kind of cool 
though....  Do we just want to print filename when at APLOG_DEBUG?
