I have a busy day today, but I will try to get it done.

I was thinking of having slots for:

- implementation
- capability name
- optional format control and format args that the programmer can use to
provide additional information.  E.g., for LW, say that it's for
licensing reasons that the DELIVER capability is not available.

If this sounds reasonable, I'll put it in, and try to find places it
should be used.

In an earlier email, Elias points out that there are related reasons why
a function might have failed.  I haven't had time to figure out whether
these would call for additional condition classes.
