Re: buffer-face-set changes the fringe, is it a bug?

And?  I really don't get it.  There are two cases:

With an omitted face in a fringe display element, either:

(1) "Emacs merges the 'fringe' and the 'default' faces, starting from 
'default' (so any color specified by 'fringe' overrides the corresponding 
color of 'default')."

or:

(2) When the 'default' face is remapped, Emacs completely ignores the 
'fringe' face, and uses the remapped 'default' face instead.
