Hi there

Sometimes `hs-hide-all' get stucked for an unknown reason.

I happens with el-get.el file (found at github:
https://raw.github.com/dimitri/el-get/master/el-get.el)

To reproduce the bug simply:

  1. run emacs: "emacs -Q"
  2. Put that in the scratch buffer:

(progn
  (require 'hideshow)
  (find-file "~/.emacs.d/el-get/el-get/el-get.el")
  (require 'hideshow)
  (hs-minor-mode)
  (hs-hide-all))

  3. Execute that code (C-x C-e)


I put a little debugging in hide-show.el (line 806):
             (progn
               (goto-char (match-beginning 1))
	       (message (format "%d %S %d:%S %d:%S %S"
				(point)
				re
				(match-beginning 0) (match-string-no-properties 0)
				(match-beginning 1) (match-string-no-properties 1)
				(match-data)))
                                ...

And I got something like:

8096 "\\(\\s(\\)\\|\\(;\\)" 8096:"(" 8096:"(" (#<marker at 8096 in emacs.d:el-get/el-get/el-get.el> #<marker at 8097 in emacs.d:el-get/el-get/el-get.el> #<marker at 8096 in emacs.d:el-get/el-get/el-get.el> #<marker at 8097 in emacs.d:el-get/el-get/el-get.el>)
8145 "\\(\\s(\\)\\|\\(;\\)" 8145:"(" 8145:"(" (#<marker at 8145 in emacs.d:el-get/el-get/el-get.el> #<marker at 8146 in emacs.d:el-get/el-get/el-get.el> #<marker at 8145 in emacs.d:el-get/el-get/el-get.el> #<marker at 8146 in emacs.d:el-get/el-get/el-get.el>) [3639 times]
Quit


The line @8146 is:
(require 'el-get-notify)		; notification support (dbus, growl...)
                                         ^
point @8146 is just after the semi-colon


I wrote a small patch that fix the bug (you can find it in attachment).

Hope that helps.
Hope that does not break anything.

Cheers
