Heh, I read the same reddit post, apparently, and fixed it like this on
master:
+The list returned has elements that contain the data from
+`file-attributes' for each file -- with the file name prepended. So
+the structure of each element is
+`(FILE-NAME FILE-ATTRIBUTE1 FILE-ATTRIBUTE2 ...)'.
+
+For instance, to get the size of the fourth element in a directory,
+you could say:
+
+ (file-attribute-size (cdr (nth 3 (directory-files-and-attributes "/"))))
+
Because (FILE1 FILE1-ATTRS) is a bit ambiguous, since it could mean
("file-name" (t 27 0 0 (23311 56666 366991 953000) (23220 586 761023 102000)
(23220 586 761023 102000) 4096 "drwxr-xr-x" t 2 66306))
instead of
("file-name" t 27 0 0 (23311 56666 366991 953000) (23220 586 761023 102000)
(23220 586 761023 102000) 4096 "drwxr-xr-x" t 2 66306)
