Jeremy Evans 58325daae3 Make String methods return String instances when called on a subclass instance ... This modifies the following String methods to return String instances instead of subclass instances: * String#* * String#capitalize * String#center * String#chomp * String#chop * String#delete * String#delete_prefix * String#delete_suffix * String#downcase * String#dump * String#each/#each_line * String#gsub * String#ljust * String#lstrip * String#partition * String#reverse * String#rjust * String#rpartition * String#rstrip * String#scrub * String#slice! * String#slice/#[] * String#split * String#squeeze * String#strip * String#sub * String#succ/#next * String#swapcase * String#tr * String#tr_s * String#upcase This also fixes a bug in String#swapcase where it would return the receiver instead of a copy of the receiver if the receiver was the empty string. Some string methods were left to return subclass instances: * String#+@ * String#-@ Both of these methods will return the receiver (subclass instance) in some cases, so it is best to keep the returned class consistent.
