Ugh. Sorry.

Hadn't thought of that... but I'll first let it sink in anyway.

(I take the double quotes as being meta-characters in this case.)

This is the thing I was thinking about. Here, `compset -q' will only
return true (and modify the parameters) in the first case, not in the
second one, because the code knows that there is/isn't a single quote 
at the beginning.

Btw. When the code automatically inserts closing quotes, this is only
done for one level. If you use `compctl -h' or `compset -q' to
complete parts of:

  % foo 'bar "baz<TAB>

the code inserts only the ", not "', and only if there is no other
suffix worth inserting.
