23.0.60; \ is considered whitespace syntax in Lisp mode?

[Drew Adams]

emacs -Q
In *scratch*, type a backslash followed by a TAB and a letter:
 
\ b
 
Put the cursor on the letter.
M-: (skip-syntax-backward "\\s-")
 
The cursor is on the backslash. IOW, it skipped not only the
whitespace but also the \, which should have escape syntax.
 
This is the first time I've noticed this, so I'm guessing there is a
good explanation and this behavior is somehow correct. But looking at
the Elisp manual, I don't get that impression. Willing to learn...

"Move point backward across chars in specified syntax classes.  SYNTAX
is a string of syntax code characters. [...]"

Oops. Thx.
