Summary
This PR updates the unterminated string error range to not include the final newline character.
This is a follow-up to #12016 and required for #12019
This is not done for when the unterminated string goes till the end of file (not a newline character). The unterminated f-string range is correct.
Why is this required for #12019 ?
Because otherwise the token ranges will overlap. For example:
Here, the re-lexing logic recovers from an unterminated f-string and thus emitting a
Newlinetoken for the one at the end of the first line. But, currently theUnknownand theNewlinetoken would overlap because theUnknowntoken (unterminated string literal) range would include the newline character.Test Plan
