Root rules should not be highlighted as "unused parse rule"

Also discussion is here: antlr/antlr4#1069

I don't think it's even possible to decide whether a rule is used or unused. So may be there should be some special highlighting for "top-level rules". That could be enough of a hint for grammar developers without being false positive about use.

Any rule can be start symbol so no way to turn off grey squiggly. it's more useful to have than not so i'll close. thanks though!

maybe add a comment like // toplevel that would turn the spurious warning?

To disable a specific rule on a specific line:

alert('foo'); // eslint-disable-line no-alert

// eslint-disable-next-line no-alert
alert('foo');

alert('foo'); /* eslint-disable-line no-alert */

/* eslint-disable-next-line no-alert */
alert('foo');

In Java it's possible to use //noinspection <Inspection name>, I'll see if it's possible to have the same thing in ANTLR.
