ls 4.5.7 sort order bug

[Jim Kunzman]

There is a bug in the sort routine for Gnu ls version 4.5.7.  I am using
Mandrake 9.1.  To demonstrate the problem:

>mkdir foo
>cd foo
>touch Test.class TestExpression.class TestExpression.java Test.java
>ls -al
total 8
drwxr-xr-x    2 jim      jim          4096 May 10 10:36 ./
drwxr-xr-x   72 jim      jim          4096 May 10 10:32 ../
-rw-r--r--    1 jim      jim             0 May 10 10:36 Test.class
-rw-r--r--    1 jim      jim             0 May 10 10:36
TestExpression.class
-rw-r--r--    1 jim      jim             0 May 10 10:36
TestExpression.java
-rw-r--r--    1 jim      jim             0 May 10 10:36 Test.java

Note that Test.java doesn't follow Test.class in the sort order.
