Issue #2449 has been updated by Yusuke Endoh. Hi, > Do you mean this IO change (multiple pushbacks and behind the > beginning) should be backported to 1.8? I move this ticket to 1.8. But it may be difficult for 1.8 that uses C's stdio to implement IO. -- Yusuke Endoh <mame / tsg.ne.jp> ---------------------------------------- http://redmine.ruby-lang.org/issues/show/2449 ---------------------------------------- http://redmine.ruby-lang.org
