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?

My apologies. Looks like this is normal. http://www.regular-expressions.info/freespacing.html

Please close this issue.
