If I put point on a letter, like this "x", (looking-at " *") returns t
but (looking-at "\s *") returns nil.
Is that intended? Is it documented?
Thanks in advance,

Gah! Sorry, missing the double backslash!
Nevermind.

Try (looking-at "\\s *")

Yes. But in
(info "(elisp) Syntax for Strings")
instead of
(info "(elisp) Syntax of Regexps")
since
(looking-at "\s *") is the same as (looking-at "s *"),
You probably want (looking-at "\\s *") instead.

In emacs 22, it is the same as (looking-at " *"),
