* eval.c (load_dyna): clear ruby_errinfo. (ruby-bugs-ja PR#409)

* io.c (read_all): make str empty if given. (ruby-bugs-ja PR#408)

* io.c (io_read): ditto.

* io.c (rb_io_sysread): ditto.

* range.c: do not override min and max.

* sprintf.c (remove_sign_bits): octal left most digit for negative
  numbers may be '3'. (ruby-bugs-ja PR#407)

* sprintf.c (rb_f_sprintf): should prefix sign bits if bignum is
  negative, using sign_bits().

* eval.c (avalue_to_mrhs): split argument passing and assignment
  conversion.

* eval.c (svalue_to_mrhs): ditto.

* eval.c (avalue_to_svalue): avalue_to_svalue([[1,2]]) should be
  [[1,2]], not [1,2] to wrap-around.
