This has been fixed on March 3 by Handa-san, see [1].  However, this fix
has side effects that I find very annoying: if I visit a file containing
only ASCII characters and insert non-ASCII characters into the buffer,
the "Select coding system" prompt pops up as well, although I never
asked about a specific coding system and would be completely satisfied
with Emacs silently choosing UTF-8[2] in that case.

2. Or whatever the preferred coding system for new files happens to be.
