The recipe to reproduce the problematic behavior was in Drew's mail:

    emacs -q
    (setq pop-up-frames t)
    M-x list-faces-display
    Click mouse-2 on completions-first-difference. It shows Inherit: bold.
    M-: (set-face-attribute 'completions-first-difference nil :inherit 
'unspecified) RET
    C-x 5 f whatever (create a new frame)
    M-x list-faces-display (from the new frame)
    Click mouse-2 on completions-first-difference. It shows "Inherit: bold" 
(the original value).

    However, doing list-faces-display from the same buffer where
    you did `set-face-attribute', and clicking
    completions-first-difference, shows "Inherit: unspecified".

My comment about a possible bug specific to :inherit was because
evaluating the same expression, namely

  (set-face-attribute 'completions-first-difference nil ATTR 'unspecified)

when ATTR is different from :inherit, e.g. :background or :slant, does
work as Drew expected, and as the doc strings say it should.
