Regexp matching whitespace including newline

Regexp matching whitespace including newline

[Nordlöw]

Is there a more compact regexp for specifying whitespace including
newlines other than:

(re-search-forward (concat "\\(" "\\s-" "\\|" "\n" "\\)*"))

I always use concat() to increase readability of my code.

Uh, (re-search-forward "\\s-") ?

That's not quite my impression.

\\s- does not match newlines in my Emacs.

May be that:

,----
| (re-search-forward "[ \n]")
`----

That depends on the syntax table, and the syntax table tends to depend
on the major mode.  When it makes sense in a particular major mode, it
should tend to match.  For example, it does so in message-mode for me.

What does C-h s show in your favorite mode?
