Re: [Bug-tar] tar with -k option no longer warns when not overwriting files

Up to version 1.22 tar would exit with a non-zero error code in such
cases.  Do you propose to restore this behavior too?  In my opinion,
it is inconsistent, because there were no real errors, so there should
be no reason for a non-zero exit code either.  Besides, that would make
it hard to discern from real error cases.

Actually, tar don't impose the -v option, since merely using
--warning=existing-file turns the warning on without having other
effects.  

On the other hand, -v turns on the otherwise suppressed warnings (not
only this particular one), because it is coherent with its main
function, which is to increase verbosity.
