bug#4153: error in `sentence-end-base'

[Štěpán Němec]

 Hello,
there is obviously an error in the `sentence-end-base' variable,
defined in lisp/textmodes/paragraphs.el (and also set in sgml-mode.el
and texinfo.el) as:

"[.?!][]\"'””)}]*"

 There are two `U+201D RIGHT DOUBLE QUOTATION MARK' characters in the
class; I suppose one of them should be different -- `U+2019 RIGHT SINGLE
QUOTATION MARK' perhaps?

 I observed the error in the latest git sources and 23.1.50.1
emacs-snapshot package.
