bug#9787: Thin line shown at full height with misc-fixed

[Stefan Monnier]

Package: Emacs
Version: 23.3

   % src/emacs -Q -f fundamental-mode --eval '(insert "toto\n" (propertize "\n" 
(quote face) (quote (:height 0.1 :inverse-video t))) "titi\n")'

Shows me toto and titi with font "xft:-unknown-DejaVu Sans
Mono-normal-normal-normal-*-12-*-*-*-m-0-iso10646-1", separated by
a thin line.  All is fine.

But if I try

   % src/emacs -Q -f fundamental-mode --eval '(insert "toto\n" (propertize "\n" 
(quote face) (quote (:height 0.1 :inverse-video t))) "titi\n")' --eval 
'(set-frame-font "-misc-fixed-medium-r-semicondensed--13-*-*-*-*-*-*-*")'

(i.e. the only change being the use of the misc-fixed font), then my
thin line because thick (uses the full height, despite the ":height 0.1").
