Unclosed double quotes in comments are hard to see

[ioRekz]

when you have something like ; hello "yo parinfer will stop working because the quote is not closed.

Doing it here for example http://shaunlebron.github.io/parinfer/demo will have the same behaviour as in nightlight but it's easier to see what's because the opening quote is highlighted.

This is harder to understand that something is wrong in nightlight cause the lonely quote is not highlighted
