Hi.  Jon the perennial nmh submarine issue problem guy.  Clearly my role is
to add code that sits quietly for at least a decade before becoming an issue.

My *intent* when adding the hook code was to allow external, non-nmh programs
to access the message store keeping track of changes.  I added this code for
a specific purpose, and never thought about anyone executing nmh commands
inside of hook code.  So I support Ken's conclusion that doing so is madness.
