The bug occurs when I contact the server from my workstation. It is
possible for me to put a new kernel on my workstation. It is not
possible for me to put a new kernel on the server.

AHAH! Test Environment Progress. I discovered that sftp allows me to log
in to my own machine, so that the workstation and server is the same
computer, using "sftp myname@localhost". And even in that context I see
the same bug. Trim it down so that there are only two zip files in my
home directory, then sftp to my own account on my own machine, and try
the key commands again -

andy@localhost's password:
Connected to localhost.
sftp> ls -l *.zip
-rw-r--r--    0 1111     1000       593050 Jun 17 10:34 ProduceLists.zip
-rw-r--r--    0 1111     1000        16642 Jul  6  2012 bangkokbase.zip
sftp> ls -l P*.zip
-rw-r--r--    0 1111     1000        16642 Jul  6  2012 ProduceLists.zip
sftp> ls -l b*.zip
-rw-r--r--    0 1111     1000       593050 Jun 17 10:34 bangkokbase.zip
sftp> exit

Here is my first test with three files -
[andy@lenny:/home/andy]: Dir *.zip
-rw-r--r-- 1 andy 28499203 Jul  2 07:52 Barcode.zip
-rw-r--r-- 1 andy    16642 Jul  6  2012 ProduceLists.zip
-rw-r--r-- 1 andy   593050 Jun 17 10:34 bangkokbase.zip
[andy@lenny:/home/andy]: sftp andy@localhost
andy@localhost's password:
Connected to localhost.
sftp> ls -l *.zip
-rw-r--r--    0 1111     1000     28499203 Jul  2 07:52 Barcode.zip
-rw-r--r--    0 1111     1000       593050 Jun 17 10:34 ProduceLists.zip
-rw-r--r--    0 1111     1000        16642 Jul  6  2012 bangkokbase.zip
sftp> exit

Try it with four files -

[andy@lenny:/home/andy]: Dir *.zip
-rw-r--r-- 1 andy 28499203 Jul  2 07:52 Barcode.zip
-rw-r--r-- 1 andy    16642 Jul  6  2012 ProduceLists.zip
-rw-r--r-- 1 andy  5618041 Jul  2 07:54 Wallpaper.zip
-rw-r--r-- 1 andy   593050 Jun 17 10:34 bangkokbase.zip
[andy@lenny:/home/andy]: sftp andy@localhost
andy@localhost's password:
Connected to localhost.
sftp> ls -l *.zip
-rw-r--r--    0 1111     1000     28499203 Jul  2 07:52 Barcode.zip
-rw-r--r--    0 1111     1000       593050 Jun 17 10:34 ProduceLists.zip
-rw-r--r--    0 1111     1000      5618041 Jul  2 07:54 Wallpaper.zip
-rw-r--r--    0 1111     1000        16642 Jul  6  2012 bangkokbase.zip
sftp> exit

Curious. It is always switching two file names, but not obvious which
ones it switches. Maybe the last two?

I will try the upstream kernel later today.
