The "diff --check" code used to conflate trailing-space whitespace error class with this, but now we have a proper separate error class, we should check it under blank-at-eof, not trailing-space. The whitespace error is not about _having_ blank lines at end, but about adding _new_ blank lines. To keep the message consistent with what is given by "git apply", call whitespace_error_string() to generate it, instead of using a hardcoded custom message.
