Hmm; this is interesting.

list-expand (C-x g) doesn't use the new completion system, and exhibits
the above-described behavior at least as far back as 3.0.6 and probably
farther.

_list_expansions (C-x d) from _expand_word should be the new completion
system equivalent, but it doesn't appear to work at all. Even just plain
_expand_word (C-x e) beeps at me, but old-style expand-word properly
expands to everything listed by list-expand.

It's a bit hard to tell from the _complete_debug trace, but it looks as
if the double quotes have already been stripped from $PREFIX by the time
_expand is called -- e.g.

: _expand:24:else; word=${(M)${(f)$(<listofthings)}:#*subthing*} 

and then a bit later

I don't quite see where the quotes are getting stripped off, unless it's
actually get_comp_string() that's at fault.  (Somebody (hi, Sven) should
update the comment around line 1028 of zle_tricky.c in any event.)
