Re: Non-escaped special chars from var expansion

I've discovered that the prior fix for the following issue is actually

The fix works for this particular case because the attempted glob with
"(baz)" generated an error. However, I've found 2 cases that don't generate
an error where the non-glob code needs to be run, but it doesn't happen
because "done_quote=1" got set.  For instance, if you just run the test
from one level deeper in that weird directory:

    mkdir foo ; cd foo ; ls $PWD<tab>

That will expand to just "ls /tmp/foo;\ bar\ (baz)/foo" (the same bad
quoting as before). Alternatively, if we name the dir with some valid glob
suffix, it also fails to quote:

    mkdir '/tmp/foo (#qN)'
    cd !:1
    ls $PWD<tab>

In both failure cases I saw that $exp was an empty string, so I tweaked the
"&& done_quote=1" part of the code (in _expand) to be "&& [[ "$exp" ]] &&
done_quote=1" and this has fixed the quoting issues I was seeing.  I'm not
sure if it is the right fix, though.
