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

[Otto Diesenbacher]

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 emacs-pretest-bug@gnu.org 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!
