* io.c (rb_io_mode_flags): preserve append mode flag.

Browse source 
[ruby-dev:24436]

* io.c (rb_io_modenum_mode): do not use external output buffer.

* string.c (rb_str_justify): differ pointer retrieval to prevent
  padding string modification.  [ruby-dev:24434]

* range.c (range_each_func): allow func to terminate loop by
  returning RANGE_EACH_BREAK.

* range.c (member_i): use RANGE_EACH_BREAK. [ruby-talk:114959]
