Description Chris Leary 2010-11-09 12:38:37 PST 
See https://bugzilla.mozilla.org/show_bug.cgi?id=576837#c2

Steps: /[C-\s]/
Expected: SyntaxError

Note that character-class/character-class range syntax like /[\s-\w]/ is accepted by the SpiderMonkey engine as an extension.

This is required for web compatibility, and permitted by the spec under section 2.

cheers, G.
