The feature is actually closed _Auto Close Braces_, and also works for other chars such as `""`, `''`, `()`, `{}`. We should change the suite name.

It's probably not critical at all, as I'd assume if it works for one, it should for the others, but if it's not too much complicated to add those additional checks (pass an array of chars to `checkCloseBrackets`, for example?, or just do several checks in the tests...)
