Hmm.  How to put this politely?  This turns out not to be true.  Backquotes
within double quotes are evaluated at command expansion time - in other words
hostname is called ONCE - during the set command.  Don't beleve me?  Try this:

set prompt="`date` > "

If the prompt ever changes, you are running something other than a vanilla
csh!!!
