Thanks a lot for the hints and pointers.

There had been changes meanwhile which hopefully address these (no
special treatment of eight-bit) along other issues (vlf-base.el).

I agree. It would be ideal for vlf if insert-file-contents would also
report the number of stray bytes at the end that haven't been utilized.

I see that vlf somehow works only by some accident with current trunk
(and --enable-checking disabled), so I'm on it. My initial attempt at
naively combining insert-file-contents-literally with
decode-coding-inserted-region though often produces wrong decoding where
insert-file-contents would be good.
