Public bug reported:
rsync 3.2.3 has a broken "--update" option. See the examples below.
The "--update" option incorrectly makes rsync say a file is newer than itself.
Remove the "--update" option, and rsync correctly says the file is "uptodate".
The right output should of course be "is uptodate" in all cases.
This bug also shows up between machines if the source rsync is 3.1.3 and the
destination is 3.2.3.
The bug does not show up if the source rsync is 3.2.3 and the destination is
3.1.3.
$ touch foo
$ rsync -avv --update foo .

foo is newer <=== THIS IS NOT CORRECT - A file can't be newer
than itself.
