Aadhavan Srinivasan 71cab59a89 Got rid of unnecessary special case to match at end-of-string ... Instead, I tweaked the rest of the matching function, so that a special check isn't necessary. If we are trying to match at the end of a string, we skip any of the actual matching and proceed straight to finding 0-length matches. This change was made because, with the special case, capturing groups weren't getting updated if we had an end-of-string match.		7 months ago
