Somewhat, but it changes the way the line looks entirely.  I'm pretty
happy having found a hack for displaying a continuous line in Emacs in
both graphical and textual frames.  Going from a line to a stripe with a
background color is a setback.

Anyway, I assume that if the workarounds consist of changing the display
of the line and this display is no bug, the best I could do would be
either living with this peculiarity or turning this issue into a feature
request.  Feel free to close this.
