Yes that is what i wanted to explain.

Of course there is no need to do this, it would change nothing, just
make the code clearer to use and read.

What can be done also is leave `dired-create-files' as it is and modify
`dired-do-create-files' to have a generic function usable anywhere
(actually it is usable only in dired) and easy to use; It is what I do here.
