[Bug-tar] avoid spurious test failure (working --listed), #24

[Jim Meyering]

[using the latest from cvs, post-tar-1.15.90]
When running `make check' on a Linux tmpfs file system, I got this:

   24: working --listed          FAILED (listed02.at:149)

Looking at testsuite.log, you can see it's not a bug in tar:

Here's a fix:

2006-02-25  Jim Meyering  <address@hidden>

        * tests/listed02.at: Sort the two lines of stderr from the
        first `tar -v --listed-incremental'.  They would come out
        reversed and provoke a test failure on a tmpfs file system.
