Subject: Removed stipulation that an empty `Bd -offset' will default to 6n. 
 Not sure where this came about.  Added regression tests to convince myself
 that this is so.  Also consolidated COMPATIBILITY notes regarding `Bd'. Added
 COMPATIBILITY note to the effect that old groff pukes on `Bd -compact
 -ragged' (regression test will fail on old groff).
