-dit(bf(--si)) Similar to the bf(--human-readable) option, but using powers
-of 1000 instead of 1024.
+The escape idiom that started in 2.6.7 is to output a literal backslash (\)
+and a hash (#), followed by exactly 3 octal digits. For example, a newline
+would output as "\#012". A literal backslash that is in a filename is not
+escaped unless it is followed by a hash and 3 digits (0-9).
+
+dit(bf(-h, --human-readable)) Output numbers in a more human-readable format.
+This makes big numbers output using larger units, with a K, M, or G suffix. If
+this option was specified once, these units are K (1000), M (1000*1000), and
+G (1000*1000*1000); if the option is repeated, the units are powers of 1024
+instead of 1000.
