Right. In the current trunk, x-list-fonts is the old way of listing 
fonts, list-fonts is the new font backend's way (but with slightly 
different arguments).  This affects X more than Windows, because 
x-list-fonts will only list X core fonts there, whereas font-list will 
list all active backends' fonts.

Once the old font code is removed, we can make x-list-fonts a 
compatibility layer on top of list-fonts, and tweak it so that it works 
with any of the supported formats (xfld, fontconfig, 
font-spec/entity/object) on input.
