Mute `skipping non-regular file` for `info=skip0` or give an option to mute them outside of `--quiet`

[JhonnyTheJeccer]

I am using rsync with --info=skip0 --no-links, but the output is still filled with skipping non-regular file messages.
This seems like a conflict to what --info=help reports:
Use OPT or OPT1 for level 1 output, OPT2 for level 2, etc.; OPT0 silences.
and
SKIP Mention files that are skipped due to options used.

Even if this is the desired result, I would still prefer to not have such messages in the output (in the log file its fine), as my SRC contains a lot of symbolic links.

I found a question on unix.stackexchange.com for my exact problem, but the solutions either do not work or are very unpractical for my usecase.

I also found two patches for similar issues, which were probably never applied:

1. mute all skip non-regular file messages with --info=skip0
2. only print skip non-regular file messages when verbose > 1

If none of the patches result in desired behaviour, I would like to suggest to add another --info option (or another rsync option) to silence all skip non-regular file messages, which could also resolve or aid #111 .

With either solution, I would also suggest to update the output of --info=help accordingly, as currently there is no mention of skip non-regular file messages not being muted by --info=skip0.

And yes, I am aware of --quiet, but I would like to still be able to have output.

Full command that is used:
sudo rsync -aAXN --fileflags --open-noatime --fake-super --info=skip0,progress2,stats3 --no-links --log-file=FILE --link-dest=DIR SRC DEST 2>&1 | tee FILE
I use 2>&1 | tee FILE because the command is constructed and executed by a python script, but I still want to see the regular output (the issue persists with executing rsync manually).

This is a bit of a tricky one since SKIP0 is the default. I don't want to turn off the skip messages by default because the messages are notifying a casual user that rsync has the horrible default of skipping symlinks. However, always mentioning expected skips is indeed annoying.

The --info=skip option is currently controlling the skipped transfer messages, not the skipped input types. I have thought of one possible solution where SKIP1 becomes the new default (allowing SKIP0 to silence these non-regular-file skips) all without sending an --info=skip1 to the remote rsync (which may be older), but this would mean that script writers that currently use --info=skip would need to change to --info=skip2, so I'm debating if this is a good idea.

Another alternative I'm considering is to make an explicitly specified --no-links option silence the message (and force the normally superfluous option to be sent to a remote receiver). I'm currently leaning in this direction.

[JhonnyTheJeccer]

I agree that the first option is probably not as good of an idea if --info=skip0 is the default (and a notification for casual users is always nice). Then the second one would also be problematic, as it might interfer with already finished projects (and changing the default of an info option sounds a bit too much in this case).

The last option is probably the best of them, as, like you said, another --no-links would not alter the behaviour of rsync, but allow better output control. And the messages would still appear when links are not explicitly excluded. Though, including those messages in the log can still be useful.

[JhonnyTheJeccer]

I have tested the new feature, but it seems the nonreg messages are also completely missing from the --log-file=FILE file. According to the manpage, the log in this file should only be modifyable with --log-file-format=FORMAT.

[WayneD]

Right, the messages are completely skipped when the user is aware of the skipping going on.

Alright, i thought this might have been a bug
