Search for "truncation_glyph".

I understand the principle, but not the particulars.  What do you
suggest that the display engine do when it bumps into the case I
described? not display the truncation glyph in that case? something
else?

IOW, what is the solution you suggest, exactly?

As Andreas points out, the reason was not the fringe, it was the
variable-width fonts.  Emacs 20 only supported fixed fonts, so it
essentially worked as a TTY display.
