I think I found the answer.  Are the following correct?

When the file is precious, Emacs already writes to a different file
first and then renames the file.  Therefore, the spot where Emacs
invokes write-region if the file is precious must already take care
of this.  At that spot, (the function called from) save-buffer just
passes the real file name as the LOCKNAME argument.

Therefore it is sufficient to pass the right filename as the LOCKNAME
argument and lookup in file-coding-system-alist and so on will use
that argument.

If this is really true, the documentation for write-region should be
updated to reflect this.  I can do that if you like.
