File names passed as arguments to emacs are opened via find-file, so in
effect the above code adds those files to file-name-history.
Yes: duplicates are (intentionally) avoided by add-to-list, and it's
not optimal to let the hook execute for every visited file when it's
only required for non-interactive (by interactive I mean those opened
via C-x C-f) file opens. Nevertheless, it's harmless, except for the
extra cpu cycles. It's just a quick hack tu put in your .emacs, but it
does the job (have you tried it?)
