Key changes include: - Removal of the word "syntax" from the lint message. More accurately, it could have been something like "syntax group" or "syntax category", but avoiding it completely is easier. - The primary lint message now reflects exactly which mismatch is occurring, instead of trying to be general. A new `help` line is general across the mismatch kinds. - Suggestions have been reduced to be more minimal, no longer also changing non-idiomatic but unrelated aspects. - Suggestion text no longer mentions changes when those changes don't occur in that specific suggestion.
