Thank you for clarifying this.  I obviously need to do my homework more
thoroughly in the future!

The ftp problem occurs because the /bin/sh shell is called with $0='-sh'
(whereas other shells have $0='+bash' etc and therefore presumably don't
regard themselves as login shells).  I'll modify profile to detect the
situation and avoid doing cd $HOME.
