There is a dangling opening paren in the default value of sentence-end-base.
I think it is not good to break the grouping construct by moving its
opening paren to sentence-end-base, and leaving the closing paren
in sentence-end.  (Also there were two typos: missing space in `Info
node' and one missing Lisp paren in texinfo.el.)  With the following
fix to your patch I can confirm that it works:

  The default value specifies that in order to be recognized as the
  end of a sentence, the ending period, question mark, or exclamation point
  must be followed by two spaces, with perhaps some closing delimiters
! in between.  See Infonode `(elisp)Standard Regexps'."
