  "message": "Get rid of redundant checks in ByteString::First() and Last().\n\nThese methods call Substr(), and Substr() performs the same check.\nLast() performs a subtraction that can underflow, but the unsigned\nunderflow is well defined, and Substr() will still reject the bad\nparameter.\n\nDo the same for StringViewTemplate and WideString().\n\nChange-Id: I1be3c4f426529cc1da13596f6800aabcc00b2cf9\nReviewed-on: https://pdfium-review.googlesource.com/c/pdfium/+/82811\nCommit-Queue: Lei Zhang \u003cthestig@chromium.org\u003e\nReviewed-by: Tom Sepez \u003ctsepez@chromium.org\u003e\n",
