* It is not extracted (because it is excluded)
* If it's not present in the archive, then an error is
reported (because the file was requested and not found)
* If it is present in the archive, no error is reported.
Previously, this would always report an error because the
exclusion prevented the entry from matching the inclusion.
Also, tar is now more reluctant to report unmatched inclusions.
Previously, "tar x file1 'file*'" against an archive that contained a
single entry "file1" would match file1 and then report an error for
the second pattern because it wasn't matched. It now considers both
inclusions to be matched and reports no error.
