Support older Zsh (version <= 5.0.4) by using [[ -n ... ]] #20

Hello! The syntax [[ $var ]] is supported starting from Zsh 5.0.6, older versions return parse error. I've replaced the conditions with [[ -n $var ]], and everything seems to work fine.

I'm doing this PR for Hacktoberfest, I hope you find it useful (this is needed by the Hactoberfest's rules).

Sorry for the late response. Thanks for this PR, I wasn't sure when the new syntax was introduced.
