extra blank line after start
Hi, I've noticed that after my shell starts, iTerm(2.9.20160206) displays an extra blank line at the beginning. This BUG does not exist in previous version(2.1.4). I'm using zsh(zsh 5.2 (x86_64-apple-darwin14.5.0)) on OS X 10.10.5. I've tried to add 'echo -n "\e]50;ClearScrollback\a"' in my .zshrc, won't work. And this line is not initially shown, if you try to select or scroll, it appears and become annoying.
To make problems worse, this blank line shows in tmux, cause incorrect cursor position(shown below): I only typed 'sleep 999' once, but it displays twice, and shows an empty line at the top.
