 foward-sexp via hideshow triggers scan error -- no error manually

Hello,

Running:
emacs -Q /usr/local/bin/latexmk -f cperl-mode --eval '(goto-char 301038)' -f forward-sexp
makes a scan error (unbalanced parenthese)

However, leaving out "-f forward-sexp" and hitting C-M-f manually once
emacs is loaded makes no error.

My guess is that there is some jit propertization/syntax-class-ization
that has to be done before C-M-f works. Evalling (message "%S"
(buffer-substring 301038 302108)) indeed shows that syntax-table
properties are used in the region. But what should be done to fix it ?

Fwiw, I encountered the problem trying to use hideshow :
emacs -Q /usr/local/bin/latexmk -f cperl-mode -f hs-minor-mode -f hs-hide-all

You probably want to call (syntax-propertize (point-max)) before calling
forward-sexp.

> emacs -Q /usr/local/bin/latexmk -f cperl-mode -f hs-minor-mode -f hs-hide-all

Maybe hs-hide-all should call (syntax-propertize (point-max)), then.

I forgot to follow up on this bug ; the following indeed worked for me :

In fact you had done that yourself two weeks ago. Closing the bug.
