This is a contradiction to my testcases.  Please check again:

In the archive, there is a member "file" (see lines 25 to 26).

In the directory "1/older/keep-newer-files", there is a file "file"
(lines 39, 40, and 62), which is OLDER than the archive member.

When extracting the archive into the directory "1/older/keep-newer-files"
(lines 82 to 85), the file should be replaced by the archive member
(because it OLDER than the archive member).

Now, look at lines 86 to 87:  The old file is removed (this is CORRECT),
but the archive member is NOT extracted, which is an ERROR.

Please run my script (in a empty directory).  What are your results?  You
don't get the error message in line 87?
