I should correct what I said before.  It doesn't force everything to 
have a single component name.  What it does is look for cases where the 
same suffix is used by more than one name, and it then produces a 
$ORIGIN directive with that suffix.

This is why it still output a line for "lists.mysql".  There's no other 
line that defines XXX.mysql.com.wl.my-company.com, so it doesn't bother 
with "$ORIGIN mysql.com.wl.my-company.com.".
