[Bug-tar] file changed as we read it

[Robert Urban]

Hi Tar people,

congrats on figuring out that it's useful to be able to suppress various
individual warnings such as the above.

It's unfortunate that suppressing the particular warning doesn't suppress tar
from fucking up the return code, i.e., I've told tar I'm not interested in the
warning "file changed as we read it", and whoopty-do, it in fact doesn't show me
the warning any more, but it still exits with a return-code of 1.

If I tell it I don't care about "file changed...", why oh why do you still think
it must exit with failure?

By the way, "--ignore-failed-read" suppresses neither the warning nor the
failure return-code.

I'm using v1.26.

cheers,

Robert Urban
