There's a simpler and faster way than all that `who am i` `ypmatch`
`awk` nonsense, given that $USER is something sane.
	set home = ~$user

This will fail abominably if $user isn't set, so it should probably be
protected with an if statement.  Something like:
	if (! $?user && $?LOGNAME) set user = $LOGNAME
	if (! $?user) set user = root
	set home = ~$user
