Fixed by the patch below.

Here I think, the second behaviour is the correct one, because `cd~opk'
is (with extendedglob) a valid pattern, meaning: match `cd' unless it
also matches `opk'. Since `cd' only seldom looks like `opk' this is
the same as saying `cd'. Right?
So the first case should be changed to behave the same as the second
one.

Btw. I'd like to express my thankfulness to all of you who send me bug 
reports for the completion code (or sugegstions for the new stuff,
or...), it's so complicated that I just can't test everything.
Thanks. And sorry that there are so many bugs.

Bye
