[Bug-tar] extract-bug with incremental backups since 1.24

[Fast Jack]

With version 1.24 a bug seems to have been introduced.  When
extracting an incremental archive (--listed-incremental), files that
should be deleted are ignored.  The script at the end of this message
demontrates this.  It creates two archives, one full backup and one
incremental.  Having created the full backup, one file is removed
before the incremental backup is created.  Extracting both archives
into another directory should result in an exact duplicate of the
source-directory.  Since version 1.24 however the deleted file still
remains in the output-directory.

I have tested versions 1.22 to 1.26.  While the 1.22 binary is the one
supplied with Ubuntu 10.04.2, the other versions were built from the
sources supplied on the tar-homepage.
Using versions 1.22 and 1.23 the diff at the end found no differences,
versions 1.24 to 1.26 resulted in:
