As a `\&#39; is not special inside a character alternative, it can never<br>remove the special meaning of `-&#39; or `]&#39;.  So you should not quote<br>these characters when they have no special meaning either.  This would<br>
not clarify anything, since backslashes can legitimately precede these<br>characters where they _have_ special meaning, as in `[^\]&#39; (`&quot;[^\\]&quot;&#39;<br>for Lisp string syntax), which matches any single character except a<br>
backslash.<br><br>`[^\]&#39;  or `&quot;[^\\]&quot;&#39; , which is right ? what is Lisp string syntax for ?<br><br>thanks<br>
