Add shutil.copyfileob(src_file_ob, dst_file_ob). shutil.copyfile() can call
it after opening the files.
Does that function make absolute sense there? Tough question. It sure
happens to work well, considered the dependent function copyfile(). I
imagine there are a bazillion functions that could be re-factored. No sense
getting overly concerned.
Put the bugger in shutil for now. Step two: propose a new organization.
