Comment :  
Changes for string.gsub with pattern ruby specs to pass. The  
following tests now pass:

String#gsub with pattern, replacement replaces & and \0 with the  
complete match  
String#gsub with pattern, replacement replaces ` with everything  
before the current match  
String#gsub with pattern, replacement replaces ’ with everything  
after the current match  
String#gsub with pattern, replacement replaces + with the last paren  
that actually matched  
String#gsub with pattern, replacement treats + as an empty string if  
there was no captures  
String#gsub with pattern, replacement maps \ in replacement to   
String#gsub with pattern, replacement leaves \ at the end of  
replacement untouched
