Keyboard macro and regexp syntax search

[address@hidden]

Here's a key sequence which searches a whitespace character with a non-
whitespace character after it and moves right to terminate the search
there (just an example):

M-C-s   \s-\S- <right>


According to the macro editor it is recorded like this:

;; Keyboard Macro Editor.  Press C-c C-c to finish; press C-x k RET to
cancel.
;; Original keys: M-C-s \ s \ S <right>

Command: last-kbd-macro
Key: none

Macro:

M-C-s                   ;; isearch-forward-regexp
\                       ;; self-insert-command
s                       ;; self-insert-command
\                       ;; self-insert-command
S                       ;; self-insert-command
<right>                 ;; forward-char-nomark



The dash (-) character is missing after the syntax matcher (\s and
\S), so the macro doesn't work at playback. Is it a bug?
