This is already documented in the Elisp manual:

       Many of the file functions take one or more arguments that are file
    names.  A file name is a string.  Most of these functions expand file
    name arguments using the function ‘expand-file-name’, so that ‘~’ is
    handled correctly, as are relative file names (including ‘../’ and the
    empty string).  *Note File Name Expansion::.
