We should document zic's behavior better, yes. As I vaguely recall, it's done 
this way on purpose and so is a feature and not a bug. Perhaps Arthur's 
less-fallible memory can cite chapter and verse about when and why the behavior 
was put into zic.

I gave the documentation a shot by installing the attached patch into the 
development version. Further improvements would be welcome.
