Bug #12477: Regexp with x modifier does not ignore space in character class

----------------------------------------
The x modifier should cause all non-escaped spaces to be ignored in a regexp, right?
But consider that

~~~
 / [a] /x =~ " "  #=> nil
 / [ ] /x =~ " "  #=> 0
~~~

So spaces inside a character class are always literal, regardless of the x modifier. This has got to be a bug right?
