Description Jonathan Wakely 2007-12-08 18:04:00 UTC 
Description of problem:
The man page shipped with RH/Fedora tar (which doesn't exist upstream) gives the
wrong semantics for --occurrence.  It claims --occurrence N will process the
first N occurrences, whereas it should be --occurrences=N and it only processes
the Nth, not 1-N.

Version-Release number of selected component (if applicable):
tar-1.17-4.fc8 and older versions

How reproducible:
Always

Steps to Reproduce:
Compare what "man tar" says about --occurrence with "info tar" or try this:

mkdir tmp || exit 
cd tmp
touch bug

tar cvf bugs.tar bug bug bug
tar --delete -f bugs.tar --occurrence 2 bug
tar tvf bugs.tar

tar cvf bugs.tar bug bug bug
tar --delete -f bugs.tar --occurrence=2 bug
tar tvf bugs.tar

none of the --delete commands do what you would expect from the man page.

Patch attached.
