First version of patch did not work with incremental archives. I corrected it, not it deals with thec correctly. I attached new version to the ticket.

When GUN Tar is used to backup user data, it may fail to archive some files because of wrong permissions on them (i.e. user did chmod 000).

It may be desired that user data would be archived anyway. 'chmod -R u+rX' could be run before 'tar -c', but if user has many files, it costs resourses and is not guaranteed that permissions will be still correct on tar invocation.

To solve this problem on our servers I created a small patch that adds --fix-permissions option, that fixes permissions on the fly if it is required.

I attached this patch (against 1.25) to the ticket. Feature request is to add this patch to the distribution :)
