- Got rid of caveat about -H not working with incremental recursion.

- Talk about how inc_recurse affects -H.
- Mention --no-inc-recursive and --no-ir options.

 Some options require rsync to know the full file list, so these options
 disable the incremental recursion mode.  These include: bf(--delete-before),

 Because of this, the default delete mode when you specify bf(--delete) is now
 bf(--delete-during) when both ends of the connection are at least 3.0.0

 explicitly).  See also the bf(--delete-delay) option that is a better choice
 than using bf(--delete-after).
