! alphanumeric or underscore characters, so the end of a word is indicated by
! whitespace or a non-alphanumeric, non-underscore character.  Note that 
! {}\code{\e b} is defined as the boundary between \code{\e w} and \code{\e
! W}, so the precise set of characters deemed to be alphanumeric depends on the
! values of the \code{UNICODE} and \code{LOCALE} flags.  Inside a character
! range, \regexp{\e b} represents the backspace character, for compatibility
! with Python's string literals.
  
! \item[\code{\e B}] Matches the empty string, but only when it is \emph{not}
! at the beginning or end of a word.  This is just the opposite of {}\code{\e
! b}, so is also subject to the settings of \code{LOCALE} and \code{UNICODE}.
  
  \item[\code{\e d}]Matches any decimal digit; this is
