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. * doc/lispref/files.texi (Magic File Names): * doc/misc/gnus.texi (Low-level interface to the spam-stat dictionary): * lisp/autorevert.el (auto-revert-find-file-function) (auto-revert-tail-mode, auto-revert-handler): * lisp/auth-source.el (auth-source-netrc-parse): * lisp/cedet/ede/files.el
