bug#3896: 23.1.50; hs-minor-mode shows only dots when function is folded

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the [email protected] mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Dear Emacs-team,

in hs-minor-mode, f.e. used in conjunction with elisp-mode or common
lisp mode, a folded function shows only three dots without the
function name as usual.

(defun foo () 
  (foo-bar))

becames to

"..."

instead of

"(defun foo () ... "

The problem seem to be introduced with a change on
'hs-hide-block-at-point in hideshow.el. Replacing that function with a
older version (before June 09) produces a folding as expected.

Thanks to the emacs-team for their great efforts!
