Take Fluent error positions from the parser divvun/fluent-rs now reports the character that actually broke an entry rather than the indentation of the line above it, so the loader no longer has to re-scan the discarded slice guessing which of three known mistakes it was. What's left is phrasing: the parser's wording assumes you know the Fluent grammar, and these files are generated, so the same few mistakes recur and are worth naming. The missing-`=` case now points where the `=` should have been rather than at the attribute it belongs to.
