Paul Eggert 662bee7d70 file-attributes cleanup
Mostly, this replaces magic-number calls like (nth 4 A) with
more-informative calls like (file-attribute-access-time A).
It also fixes some documentation and minor timestamp coding
issues that I noticed while looking into this.
* doc/lispref/files.texi (File Attributes):
* lisp/files.el (file-attribute-size)
(file-attribute-inode-number, file-attribute-device-number):
* src/dired.c (Fdirectory_files_and_attributes)
(Ffile_attributes):
Mention which attributes must be integers, or nonnegative integers,
as opposed to merely being numbers.  Remove no-longer-correct
talk about representing large integers as conses of integers.
