I'm fine with arg_print_missing suppressing lazy fetching (when I
rebase my patches on this, I'll have to ensure that fetch_if_missing
is set to 0 if arg_print_missing is true), but I think that the
behavior when arg_print_missing is false should be the opposite - we
should let has_object_file() perform the lazy fetching, and die if it
returns false (that is, if the fetching failed).
