Re: matching multiple families in <alias> and <test>

i. e. prepend/append occurs around the leftmost/rightmost actually matching

Aha. that looks reasonable to me. particularly if the result is
considered as the intersection of the given pattern and the string
sets in<test>.

Right, that was the word :-)
But I don't think it's a good idea anymore, because I can't think of any way to consistently deal with "assign" edits then.

What I can also think of (at least for<alias>), is to not use FcOpComma,
but create as many FcTest objects (and add all of them with FcConfigAddEdit)
in FcParseAlias as there are families in the upper part of<alias>, thus
simulating what a user would do creating separate rules for all of them.

Sure. that would be an idea though, as it's documented,<alias>  has to
be kept as a syntactic sugar. so needs to change the behavior of
FcOpComma then.

True, it's not a good approach to invalidate existing user-knowledge about the relationship of <alias> and <match>.

Maybe when going through the FcOpComma operands, one could tag the matching FcValueList's somehow and loop precisely over them for the following prepend/append/assign edits.
