json-next gem - read generation y / next generation json versions (HanSON, SON, JSONX/JSON11, etc.) with comments, unquoted keys, multi-line strings, trailing commas, optional commas, and more

I was parsing a JSON document that had an extra comma, and when trying to clean it up it produced an infinite loop and threw a format error.
input = " {\"foo\":\"bar\",,}"
JSONX.convert(input)
throws

!! format error: string literal - expected opening quote (") - rest is >>}<<

Hi. I'd like to submit back a small modification to pattern.rb in the json/next gem.
When I was using JSONX.parse I kept getting this warning:
/var/lib/gems/2.3.0/gems/json-next-1.2.1/lib/json/next/parser/jsonx.rb: warning: character class has duplicated range
/var/lib/gems/2.3.0/gems/json-next-1.2.1/lib/json/next/parser/jsonx.rb:77: warning: character class has duplicated range
That warning is pointing out that in regular expressions, \w already covers _, so you don't need to have both in the pattern. Personally, it seems silly to make a whole warning about that - a little regex redundancy is hardly worth taking up anybody's time. But warnings can be annoying. I edited pattern.rb so that the three instances of this:
\\w_
are changed to just this:
\\w
That made the warning go away. Of course, I don't know if it will make other warnings or errors appear. But hopefully this can fix this small problem.
:-)
