** The 'utf-8-auto' coding-system now produces BOM on encoding.
This is actually a bugfix, since this is how 'utf-8-auto' was
documented from day one; it just didn't behave according to
documentation. It turns out some Lisp programs were using this
coding-system on the wrong assumption that the "auto" part means some
automagic handling of the end-of-line (EOL) format conversion; those
program will now start to fail, because BOM signature in UTF-8 encoded
text is rarely expected. That is the reason we mention this bugfix
here.
In general, this coding-system should probably never be used for
encoding, only for decoding.
