[Bug 228069] tar(1) fails to append newer files only (-u, --update), but always appends all files (like -r).

Thanks for the explanation!  I generally use --posix (pax format) when it comes
to backups, path length is (was) another reason.
Hopefully I'll find some time in early winter to work on some of my own
(easy-skill) topics, but I guess a proper fix isn't most trivial for this one.
What I also remember is that pax(1) - natively providing the only storage
format suitable to do backups - doesn't utilize libarchive(3).  Not sure if
this has changed meanwhile.  I was off from such topics for a while and not
sure if libarchive(3) is the place to fix tar(1), which got high frequency
updates back then.  Happy to see this PR wasn't closed with [no fix|not a
bug|etc] :-)
