as a non-native i had some trouble to correctly parse the term "all
but useless", but after a websearch came to my rescue, i agree.

what's more: i really think that $0 expanding to (float)'0' is a BUG.

unless we acn assign something *useful* to $0-in-msgboxes, i think it
should stay undefined, much like an argument out of range.

oh yes.

it's a pity that this is unlikely to happen (for compat reasons), but
imho it's the only sensible expansion to $0 - in any context.
