Thanks a lot, Stefan, for your precious answers!

I did not know jit-mode.  Is it recent?  Does it replace lazy-lock?

When I start "emacs -Q .emacs", for example, I get the following:
M-: jit-lock-mode
=> t
M-: (memq 'jit-lock-mode minor-mode-list)
=> nil

Can you tell me why jit-lock-mode does not appear in the list of minor
modes?

Thanks!  It's very simple and fast enough for my function, but...

Well, to answer Eli's question (why do I need that), I would say that
checking the text-properties was the solution I imagined to determine
whether the point is inside a string or a comment, for example.

Now, Stefan tells me there is an API to the syntactic parser.

Woah!  It's like opening a door to a rich and exciting new world!

I took a look at syntax-ppss and parse-partial-sexp documentation.
It says it parses *Lisp* syntax.

Is it a bug in the documentation?

Before I go any further in the tests and doc (which is far for being
perfectly clear to me, at first glance!), can you tell me if I can use
it in other modes than emacs-lisp, like C-like modes, for example?

Actually, I'm currently working on shell scripts (in sh-mode[pdksh]).
Does it handle the whole syntax:
"..." '...' `...` {...} [...] [[...]] $(...) etc?

Thanks in advance
