 Page 191:
 for REs:
        \c      matches the escape sequence or literal character c
 for strings and REs:
        \c      any other character 'c' literally, e.g., \" for " and \\ for \
 (also shown on p. 31-32 and discussed in some detail on p. 28-29)
 The implication is of course that all 'x' are valid in '\x' and thus  
 no warning should ever be given.  (except inside a character class in  
 an RE where only '\', '^' at the beginning, and '-' between two  
 characters have any special meaning)
