+; These are a bit opinionated since some people just indent binary/ternary expressions spanning multiple lines.
+; Since they are only triggered when a newline is inserted into an already complete binary/ternary expression,
+; this should happen rarely, so it is not a big deal either way.
+; Additionally, adding these queries has the advantage of preventing such continuation lines from being used
