Unfortunately that's too hard to arrange, as context-free strings would 
become too long be practical for tzselect to use in its messages. I 
expect the best we can do is make things work reasonably well for the 
sort of contexts that 'tzselect' uses, and hope that other programs use 
similar contexts. (This is not to say that we couldn't improve tzselect 
to make the contexts clearer.)
