Re: [BUG] "git clean -df ." silently doesn't delete folders with stale .nfs* files

I have tried to reproduce your situation using git 2.43.0 without success.

$ mkdir test

Removing .nfs12309

I suspec that this is different from a real NFSv3 client in that
removal of such "removed while still open" files would result in
another one automatically resurrected by the filesystem.

In any case, if we cannot remove a file (due to filesystem
limitation), we should report the fact, just like in a case
where we cannot remove a regular file, e.g.

    $ cd git.git/
    $ mkdir -p junk/ttt
    $ >junk/ttt/sss
    $ chmod a-w junk/ttt
    $ cd junk
    $ git clean -f -d -x ttt; echo $?
    warning: failed to remove ttt/sss: Permission denied

Figuring out why it is not happening is left as an exercise to
readers ;-), as I no longer have an NFSv3 environment handy.

Thanks.
