2016-02-26	Make sure formatter errors are emitted by the default Write::write_fmt	Ulrik Sverdrup	-0/+54
	Previously, if an error was returned from the formatter that did not originate in an underlying writer error, Write::write_fmt would return successfully even if the formatting did not complete (was interrupted by an `fmt::Error` return). Now we choose to emit an io::Error with kind Other for formatter errors. Since this may reveal error returns from `write!()` and similar that previously passed silently, it's a kind of a [breaking-change].
