The problem is, which font to specify explicitly? Not all platforms have 
a font named "Courier". Mine doesn't (Fedora 23). If we knew that all 
Emacs platforms had an appropriate font (Courier, or FreeMono, or Nimbus 
Mono L, or whatever), we could specify that font, but I do not know of 
any such font, nor do I know how to query arbitrary platforms for such a 
font.

In further testing on my Fedora 23 host I discovered another suitable 
anti-aliased font, Courier 10 Pitch. It is also a free font and looks a 
bit better with emacs -Q, and Wikipedia says Courier 10 Pitch BT is the 
default Courier font on many GNU/Linux hosts 
<https://en.wikipedia.org/wiki/Courier_%28typeface%29#Courier_10_Pitch_BT>. 
So I will update my proposed patch to prefer Courier 10 Pitch to the 
alternatives already in the list.
