You're quite right that this should work better, but I suspect fixing it is
a real pig.  Quoting is one of the messiest parts of completion (regular
viewers will know this is rather a strong statement).  I think fixing it
properly by leaving all quoting in place isn't going to be easy (to put it
mildly).

I think you have a workaround, though: use an initial single quote.  Not
only does that get kept, the closing single quote is put in place
afterwards.  Is this good enough?  (It would be good to document this but
goodness knows where it goes.)
