Auto/undecided
This is not expected. It's not hard to imagine the code the leads to
this result, but it's incorrect; we'll fix it. (I don't see a hurry,
it may take some time. Patches welcome!) The undecided coding system
is a sentinel, and should always be changed as the end result of
autodetection, presumably to default-buffer-file-coding-system in the
case
I’ve a patch below.

This is a different bug (a user could set buffer-file-coding-system).
In the case of buffer-file-coding-system(-for-write) being 'undecided
or similar, the writer function (output might not be to a file) should
error.

And this is a third bug. I thought Aidan had fixed this, but I guess
it's only for his new unibyte coding systems.
No, not even for them. It’s in progress,
http://mid.gmane.org/18912.40510.593475.645687@parhasard.net is the bones of
it, but more work is needed, in particular implementing the checks for the
Win32-specific coding systems and erroring in the appropriate places when
data will be lost. My evenings and my weekends are my own, right now,
thankfully, I hope to see some progress this month.

Set buffer-file-coding-system more sensibly with zero-length files.

If the file was zero-length, used-codesys (and thus
buffer-file-coding-system) is undecided. Set it to a more sane
value.
