Open question: Do we have consensus that we’ll just tweak the error message for now, no location tweaks? (Location info would require reporting one violation per character instead of per literal.)

I’m 👎 (but not strongly) to location info, because I think the characters showing up in the lint message is already a huge win for 99% of use cases. If users want line/column info and create an issue to that effect, we can reconsider then. That’s just my thought on the matter, others may disagree.
