Kent, you misunderstood ... I think.  By lowercase, I don't mean to make
everything lowercase.  Capitalizing initial letters of sentences looks
nice, and when typing out a function name, or variable name in an error
message, the uppercase PNAME is FINE.  I think upper-case only messages
are very impersonal.  Distinguishing between computer output and user
input can be relatively accomplished by wise choices of spacing.  

You said, "In the final analysis, if you care about case, you....".
What we are advocating is not user-written error messages, but LISP
interpreter error messages.
