* string.c (rb_str_slice_bang): if there's no corresponding
substring, slice! should return nil without exception. * array.c (rb_ary_insert): type fixed. * string.c (rb_str_split_m): accept separator value nil as well. * string.c (rb_str_become): was leaking memory. * class.c (rb_include_module): should not alter other classes/modules by inclusion. by this fix, local order may not be preserved for some cases. * class.c (include_class_new): module may be T_ICLASS; retrieve original module information. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@2632 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
