I think that the description of wal_sender_timeout and its properties
should remain where the parameter is defined, so (3) is not a good
option in my opinion.  (2) has a point with the use of quotes actually,
so why not just mention options=''-c wal_sender_timeout=5000'' in the
example of recovery.conf as you suggest and call it a day, but keep the
paragraph I suggested in (1)?
