I've seen these continuation glyphs on every TTY display where I ever
used Emacs, so I'd consider it a surprise, if not a bug, that on some
TTYs those continuation glyphs were absent.  They should be there to
indicate to the user that the line is continued.

Sorry, I cannot want videos of this format.
