I just said this in the other thread, but to repeat it in the
right place: I think we should expand out the case statement
to explicitly list the --thingydir options it is supposed to
be matching, and drop the wildcard: as this bug demonstrates
it's rather easy to accidentally shoot yourself in the foot
with it.
In fact, what cases is this supposed to be matching? All
the documented --thingydir options are handled explicitly
earlier in the case statement.
Paolo, you added this case in commit 6bde81cb0, but the
commit message doesn't give any rationale; what's it for?
