I've now sqashed the commits into one. |
As reported in sunfishcode/is-terminal#18, there are situations where `GetFileInformationByHandleEx` can write a file name length that is longer than the provided buffer. To avoid deferencing memory past the end of the buffer, use a bounds-checked function to form a slice to the buffer and handle the out-of-bounds case. This ports the fix from sunfishcode/is-terminal#19 to std's `is_terminal` implementation.
