Please change your mailer settings to wrap text at 70 characters or so.
It looks rather funny when an entire paragraph's text scrolls away in
one single line.

This sets the prompt only once.  To have PS1 updated each time you
change your working directory, you can do one of two things:

a) Install bash from the ports (shells/bash1 or shells/bash2), and set
   your PS1 in .bashrc with:

	export PS1='\u@\h|\w\$ '

b) Make `cd' a shell function, that calls `chdir' to do the actual
   change of the path, and updates PS1 with `pwd` again.  Something
   like:

	cd () {
	    chdir "$@";
	    PS1="$USER$`hostname | cut -d. -f1`|`pwd`$ ";
	    export PS1;
	}

   of course, this is an ugly cludge, since if you use `chdir' instead
   of `cd', your PS1 will not be updated :/
