What a delicate way to make a bug report. 8-)

I am deep into MiniVend 4 now, so I probably won't fix this one
as it has existed for almost 2 years without repercussions.

The relevant change would be:

<	$::Values->{$var} = $set if defined $set;
<	$value = $::Values->{$var} || '';

>	$::Values->{$var} = $set if defined $set;
>	$value = defined $::Values->{$var}
>			?  $::Values->{$var}
>			: '';

It had already been fixed in 4.0 when I added the filtering stuff.
