Mis-parses regular expression with a / inside a character class

[GoogleCodeExporter]

Here's the code:

    var patterns = {
        traditional:
/^(?:[A-Za-z0-9+/]{4})*[A-Za-z0-9+/]{2}(?:[A-Za-z0-9+/]{2}|[A-Za-z0-9+/]=|==)$/,
        urlSafe:    
/^(?:[A-Za-z0-9\-_]{4})*[A-Za-z0-9\-_]{2}(?:[A-Za-z0-9\-_]{2}|[A-Za-z0-9\-_]=|==
)$/
    };

The mis-highlighting begins at the / within the character class in the 
first pattern, which your parser interprets as the end of the pattern.  

The obvious work-around is to use new RegExp for patterns that contain
slashes, which is honestly a pretty good idea in the first place.

Cool!  You've found a bug in Mozilla Rhino's parser that I copied during my 
port. 
I'll report it over in Rhino-land and get it fixed here ASAP.

This is fixed in the svn repository, and will be in the next release.

It was great to hear back from you on this. Awesome that you're feeding it back 
into
Rhino. :-)
