   @item version
   The @code{version} test may be used to perform comparisons against
   specific Readline versions.
   The @code{version} expands to the current Readline version.
   The set of comparison operators includes
   @samp{=} (and @samp{==}), @samp{!=}, @samp{<=}, @samp{>=}, @samp{<},
   and @samp{>}.
   The version number supplied on the right side of the operator consists
   of a major version number, an optional decimal point, and an optional
   minor version (e.g., @samp{7.1}). If the minor version is omitted, it
   is assumed to be @samp{0}.
   The operator may be separated from the string @code{version} and
   from the version number argument by whitespace.
   The following example sets a variable if the Readline version being used
   is 7.0 or newer:
   @example

   @item variable
   The @var{variable} construct provides simple equality tests for Readline
   variables and values.
   The permitted comparison operators are @samp{=}, @samp{==}, and @samp{!=}.
   The variable name must be separated from the comparison operator by
   whitespace; the operator may be separated from the value on the right hand
   side by whitespace.
   Both string and boolean variables may be tested. Boolean variables must be
   tested against the values @var{on} and @var{off}.
   The following example is equivalent to the @code{mode=emacs} test described
   above:

   @item bracketed-paste-begin ()
   This function is intended to be bound to the "bracketed paste" escape

   It allows Readline to insert the pasted text as a single unit without treating
   each character as if it had been read from the keyboard.  The characters
   are inserted as if each one was bound to @code{self-insert} instead of
   executing any editing commands.
   
   Bracketed paste sets the region (the characters between point and the mark)
   to the inserted text. It uses the concept of an @emph{active mark}: when the
   mark is active, Readline redisplay uses the terminal's standout mode to
