bug#2714: 23.0.91; set-default-font incorrectly changes font height?

bug#2714: 23.0.91; set-default-font incorrectly changes font height?

[Miles Bader]

When I use `set-default-font', it seems to affect the font-height even
though I explicitly tell it to only change the family.


To reproduce:

 (1) Start emacs with:  emacs -Q

 (2) Evaluate the following in *scratch*:

        (set-default-font "Liberation Mono-8")
 
     Notice that the font is now fairly small, as I specified an 8-point font.

 (3) Evaluate the following in *scratch*:

        (set-fontset-font nil 'unicode
                          (font-spec :family "Dejavu Sans Mono")
                          nil 'prepend)

 (4) ** Notice that the default font size has changed to become fairly
     large , even though I explicitly specified only the family to
     `set-fontset-font'. **

 (5) I can then force the size back to the original correct size using:

        (set-face-attribute 'default nil :height 80)


[Hopefully you have those two fonts on your system, as they're common
free fonts; however any two scalable fonts will probably work.]

Thanks,

-Miles

I've just installed a fix.   Could you please try again
with the latest code?
