If people who use this mode don't object to seeing that marker always,
I don't mind, either, although as I said we already have another means
of indicating the end of the buffer.  Feel free to do a user poll.

In any case, we'd need to come up with an ASCII character, because
Unicode characters might not be available on TTYs.
