Brandon Casey cd163d4b4e usage.c: detect recursion in die routines and bail out immediately ...

It is theoretically possible for a die handler to get into a state of
infinite recursion.  For example, if a die handler called another function
which itself called die().  Let's at least detect this situation, inform the
user, and call exit.
