Have sorted these out on my local copy.

But, what to do about things like affected_rows and insert_id which 
return 0 if not connected but could be considered exceptional?

Also Query::escape_string(char*...) attempts the connected path when not 
connected so presumably this needs a check too?

Is there a bigger issue of "programmer's responsibility" here?
