Bug #1312: String#rindex(Regexp, offset) doesn't seem to match greedily

I may be wrong but I was expecting:
"abcdefg ".rindex(/\w+/,10)
to return 0.

This is what actually happens:
irb(main):003:0> "abcdefg ".rindex(/\w+/,10)
=> 6
irb(main):004:0> $~
=> #<MatchData "g">
irb(main):005:0> $[0]
=> "g"
irb(main):006:0> $.offset(0)
=> [6, 7]

The Regexp seems to match in a non-greedy way. The /\w+/ only matches the "g". I was expecting it to be greedy and match "abcdefg" and return 0 instead of 6.

Please correct me if I'm wrong in my expectation.

Thank you,

David

Wrong expectation.
String#rindex returns the rightmost position can match.
