Subject: [ruby-core:23533] Re: [Bug #1487] String#each_char must return 	self

As per Eero Saynatkari's suggestion, my response is:

This change was made to bring #each_char in line with all the other
#each* methods which all return self, not a copy. It should follow the
same pattern unless there is a crucial reason not to, and in that case
it must be clearly documented.
