[Bug 1965076] Re: rsync --update incorrectly reports file "is newer" than itself

[Ian! D. Allen]

Your incorrect statement "seems the issue does not actually exist" is
wrong.  I told you exactly how to reproduce the problem on your latest
22.04.1 LTS release.  I gave you the link to the upstream bug that Wayne
fixed over two years ago.  This two-year-old bug does exist and it
exists in your most recent Ubuntu 22.04.1 LTS release.  Here's another
way to show the bug:

    $ touch foo
    $ rsync --update --info=skip foo foo
    foo is newer

Obviously a file should not be listed as newer than itself.  This rsync
is broken.

The real bug appears to be that Ubuntu is shipping a broken two-year-old
year 3.2.3 version of rsync in its latest 22.04.1 LTS release and won't
update it to get rid of the bug.  I've added a comment to the github bug
number 98 warning people about the broken Ubuntu LTS.

All my scripts that depend on an accurate "is newer" indicator from
rsync are broken.

Title:
  rsync --update incorrectly reports file "is newer" than itself

Status in rsync package in Ubuntu:
  Invalid

Bug description:
  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 .
