Yes, I *could* do that.  However, if I did I would simply be covering
up a problem which ought to be a problem for many programs other than
dpkg but which isn't solely because of sloppy programming.

If I add any code to dpkg with respect to this it'll be a check which
makes it bomb out with an informative message.  See, for example, my
approach to trying to run dpkg with a bad PATH.
