I didn't say renaming doesn't work, I only got that inappropriate
message.  Maybe just because I had edited the buffer by hand to make the
loop terminate.

I'm not convinced that this is not an intended use case. - on the
contrary.  Everything works, basically, it just seems that some details
in the code are not prepared for some things that are slightly
different, e.g. the final line in those buffers.

Please don't just signal an error unless you are really sure that this
never worked and was never intended to work, and is not easy to fix.

Michael.
