Sure.

Thank you for updating. 
Just one comment for the code.

+       if (dopt.do_nothing && !(dopt.dump_inserts || dopt.column_inserts))
I think you can remove dopt.column_inserts here because at this point dopt.dump_inserts has
already turned true if --column-inserts is specified. 

But I'm just inclined to think that use case of this feature is vague.
Could you specify more concrete use case that is practical for many users?
(It would lead to more attention to this patch.)
For example, is it useful to backup just before making a big change to DB like delete tables?
