Title: Fixed Mac OS X Terminal.app related issue with extra newlines echoed

See: http://stackoverflow.com/questions/9029921/zsh-outputting-extra-newlines-when-echoing-a-multiline-variable/9030611#9030611 for an example of the issue in action.

I found that the real root of the problem was an issue with with Terminal.app handling the tab/window titles getting updated.
