rsync  version 2.6.5  protocol version 29

Rsync is broken and now claims that all linked files are not "uptodate".

Create a directory and two files:

    bash-3.00$ mkdir a
    bash-3.00$ date >a/foo
    bash-3.00$ date >a/bar

rsync the directory; note a/foo and b/foo get updated:

    bash-3.00$ rsync -avvH a b
    building file list ...
    done
    created directory b
    delta-transmission disabled for local transfer or --whole-file
    a/
    a/bar
    a/foo
    total: matches=0  tag_hits=0  false_alarms=0 data=58
    sent 265 bytes	received 70 bytes  670.00 bytes/sec
    total size is 58  speedup is 0.17

rsync the directory again; note that a/foo and b/foo are "uptodate":

    bash-3.00$ rsync -avvH a b
    building file list ...
    done
    delta-transmission disabled for local transfer or --whole-file
    a/bar is uptodate
    a/foo is uptodate
    total: matches=0  tag_hits=0  false_alarms=0 data=0
    sent 127 bytes	received 38 bytes  330.00 bytes/sec
    total size is 58  speedup is 0.35

Change a/bar to be a link to a/foo:

    bash-3.00$ rm a/bar
    bash-3.00$ ln a/foo a/bar

Remove the destination directory and rsync:

    bash-3.00$ rm -r b
    bash-3.00$ rsync -avvH a b
    building file list ...
    done
    created directory b
    delta-transmission disabled for local transfer or --whole-file
    a/
    a/foo
    a/bar => a/foo
    total: matches=0  tag_hits=0  false_alarms=0 data=29
    sent 212 bytes	received 60 bytes  544.00 bytes/sec
    total size is 58  speedup is 0.21

rsync the directory again; note that only a/bar is listed as "uptodate",
and rsync incorrectly says it needs to update a/foo:

    bash-3.00$ rsync -avvH a b
    building file list ...
    done
    delta-transmission disabled for local transfer or --whole-file
    a/bar is uptodate
    a/foo
    total: matches=0  tag_hits=0  false_alarms=0 data=0
    sent 138 bytes	received 39 bytes  354.00 bytes/sec
    total size is 58  speedup is 0.33

Repeating the rsync, it always says the same (incorrect) thing.
