I think it obvious: if a BOM mark gets detected on read, one wants to
have it removed from the buffer and reinserted on saving the buffer.

I am just not sure what the semantics for recoding/encoding/decoding
regions are.  They should not mess with BOM in any case, I would
suppose.  But then reading a file is not equivalent to reading it
literally in unibyte mode and then decoding the buffer-region.

Maybe there never was such an equivalence (can't be for shift codes, can
