I've read the comments now, and it sounds rather difficult to get it 
right. (I typically work around such situations by duplicating rules in 
the config, i. e. effectively appending/prepending my edits several 
times during config substitution.)

I think that most users, when they use multiple families in the upper 
part of <alias>, think of something like:

   "Now if I use <accept>, then append after the last occuring
    value out of the ones I just specified"

and

   "If I use <prefer>, then prepend before the first occuring
    value out of the ones I specified"

I. e. maybe something like having FcConfigMatchValueList() return first 
_and_ last match in the actual value list and use the latter for append 
edits.

But I don't really know. I'm fine with the current implementation and 
it's easy to avoid such configuration issues anyway.
