- [zendframework/zend-diactoros#222](https://github.com/zendframework/zend-diactoros/pull/222) fixes the
`SapiStreamEmitter`'s handling of the `Content-Range` header to properly only
emit a range of bytes if the header value is in the form `bytes {first-last}/length`.
This allows using other range units, such as `items`, without incorrectly
emitting truncated content.
