Some RRRS comments/corrections

[SUSSMAN@G.BBN.COM]

Here are a few things we noticed while documenting Butterfly Scheme:

CI in string and character procedure names:
  You describe it as a suffix, and give its relationship to the ? suffix.
But it is generally embedded earlier in the name (not ...ci?).  You probably
want to just say they have CI in their names.

DO:
   The expressions after the <test> are optional according to the text,
but the template shows one or more expressions.  Apparently it is the
template that is wrong.

TRUNCATE:
   The description is incomplete -- note that it fails to specify
the sign of the answer.
