** String changes:
-*** The escape sequence \s is now interpreted as a SPACE character.
+*** The escape sequence \s now stands for the SPACE character.
-Exception: In a character constant, if it is followed by a `-' in a
-character constant (e.g. ?\s-A), it is still interpreted as the super
-modifier. In strings, \s is always interpreted as a space.
+`?\s' is a new way to write the space character. You must make sure
+it is not followed by a dash, since `?\s-...' indicates the "super"
+modifier. However, it would be strange to write a character constant
+and a following symbol (beginning with `-') with no space between
+them.
+
+`\s' stands for space in strings, too, but it is not really meant for
+strings; it is easier and nicer just to write a space.
*** A hex escape in a string constant forces the string to be multibyte.
