impl AddAssign<char> for String

[Timmmm]

Is there any reason there is an impl AddAssign<&str> for String, but not impl AddAssign<char>? Anyway it's something I would expect.

FYI, it was implemented for &str because there was already a stable implementation of Add<&str>. See #34890.

Seems like something we shouldn't track, but would probably accept a PR for.
