+* Specify parameter ID-FORMAT in all calls to `file-attributes' and
+ `directory-files-and-attributes' where attributes UID or GID are used.
+ Whenever possible, use value 'string.
+ When done, change meaning of default value from 'integer to 'string.
+ If value 'integer is used nowhere, remove the parameter ID-FORMAT from
+ the definition of `file-attributes' and `directory-files-and-attributes'
+ and from the calls.
