It was probably me who proposed something like the following. I suspect it
never worked because contrary to what I thought the exclude = yes matches
nothing. So, I have two suggestions that may work:
1. Add a
wild = "*"
just after the exclude = yes
2. Alternatively, and probably better, add a
regex = ".?*$"
just after the exclude = yes.
I would be interested to know if this works or not.

This is why I thought the above would work, but I think in fact that the above
is wrong. On the other hand, if one drops out of all the Options, and nothing
has matched, then everything is matched, and the Options from the last
Options are used (but apparently not the exclude -- I'm going to look into
this).

Yes.

Probably not true.

Please let us know if my suggestions above help ...
