Cannot pipe yes to zk init

[j-hui]

I'm used to piping yes to interactive programs for which I want to automatically hit <CR> for each prompted item. However, this does not work with zk:

$ yes '' | zk init

I'm aware I can do zk init --no-input to accomplish what I intended to do in the first place, so this is not a big issue, but I wanted file this issue in case others run into it too, and in case this is a very easy fix.

It looks like an issue in the third-party library AlecAivazis/survey. Feel free to open an issue on its repo if you want. As it's not a common use case / issue for zk, I'll close this for now.

Got it, thanks! This seems to be related to AlecAivazis/survey#394
