I narrowed down one of the bugs I mentioned here (and fixed it): bug#54603.

There are still a few other issues with quoting/escaping in argument 
predicates/modifiers. I can work on fixing these in a separate bug, or 
update my patches in this bug if you prefer. I lean very slightly 
towards the former, since the quoting/escaping logic could use some 
changes to be more consistent. That seems different enough from this bug 
that I think it'd be simpler to separate them. That said, if you'd 
prefer I do this all in this bug, that's ok too.
