&str is a "particle" of a string already, see the graphemes iterator, so it seems natural that we should be able to use it with Extend.

This will need an RFC. |

I do not think this needs an RFC. the RFCs repo states that an RFC is for a substantial change and I do not think this change requires one. @aturon thoughts on this? |

Yeah, this is quite minor and we could accept a PR for it without an RFC. |

Strings iterate to both char and &str, so it is natural it can also be extended or collected from an iterator of &str. Apart from the trait implementations, `Extend<char>` is updated to use the iterator size hint, and the test added tests both the char and the &str versions of Extend and FromIterator.
