one instance inside the copy hierarchy.  (Used to fail with protocol 29
or --no-ir.)

file-entry values affected by HLINK_BUMP() stay put.

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

the generator.

- Incremented SUBPROTOCOL_VERSION to 7.

the code to use the structures and functions calls.

- Tweaked a {read,write}_varint30() call set that didn't need to be "30".

to support 2 sizes of key (32 and 64 bits), and to have a non-allocating
option for the find routine (returning NULL for no match).

all the time-preserving semantics into preserve_times.

what is being expanded.

rsync.  Just make them a no-op.

so the code could try to free an extent twice in certain circumstances.
