I think there might be another one with the font selection.

If you do set-frame-font with one of the installed fonts that show up  
in a completion buffer, you sometimes get an error:

set-frame-font: Font `-apple-frutiger-roman-medium-r-normal--0-0-0-0- 
m-0-iso10646-1' is not defined
Making completion list... [3 times]
set-frame-font: Font `-apple-frutiger-roman-medium-r-normal--0-0-0-0- 
m-0-mac-roman' is not defined

Also, the following font

-apple-helvetica ce-medium-r-normal--14-140-75-75-m-140-mac- 
centraleurroman

can't be set, instead, it just uses the default Monaco font.

Furthermore, it seems that the fonts don't exhibit the same spacing  
as in other applications. For example, a Helvetica Medium 12pt font  
is much narrower as for example in Apple Mail, where this is the  
default font (I think).
I wouldn't say that this looks bad, it's just not conforming to the  
standard.

Apart from that, I'm very grateful for ATSUI support. Variable-width  
fonts finally look good and readable. Your patch is a tremendous  
improvement.
