already in use. However, if @var{unique} is non-@code{nil}, it modifies
@var{newname} to make a name that is not in use. Interactively, you can

Most Emacs Lisp file-manipulation functions get errors when used on
files that are directories. For example, you cannot delete a directory
and so on to any number of levels. However, recursive copying does not
take place when the definition of a character is a symbol whose function
definition is a keymap; the same symbol appears in the new copy.
