Sorry for jumping in late without having followed the whole discussion.  Here's 
a naive question: is there any reason to use an actual glyph from a face to 
draw that line, rather than just a continuous line?

A good analogy might be the way window separators ("vertical borders") are 
drawn: when I use a non-graphical Emacs it uses a series of '|' characters to 
draw separations between windows, but when I use a graphical Emacs (with 
scroll-bars-mode off) it draws a solid black line, or at least that's what I 
understand from e.g. 
https://lists.gnu.org/archive/html/help-gnu-emacs/2013-01/msg00257.html.

Sorry if I missed something obvious.
Clément.
