You know that you can say " " instead of "\s", right? This is because,
in string literal syntax, "\s" is special and replaced by a space
(analog to "\n", "\r" and friends). This has nothing to do with
regexps: the regexp engine gets to see the " ".
So it's the same as "[ ]+ ".
This is a row of one or more spaces, followed by a space -- which is
the same as a row of two or more spaces, which can be also written
" \\{2\\}" (remember: one backslash for the Lisp string, one for the
regexp).
Cheers
